Hawk Ridge Nature Reserve BioBlitz #2

It was mentioned last year and I will say it this year: A BioBlitz is an incredible thing! Even the most familiar places can hold new secrets. For me, the trails at Hawk Ridge Nature Reserve, are, in part, familiar territory. A trail, however, is an ever changing landscape. Last year, almost to the day, a massive wind storm toppled many large, mature trees in the Duluth area and Hawk Ridge was no exception to losses. Many of these trees were great trail markers and "old friends" to observe as you made your way to Summit Ledges or toward Amity Creek. Since the wind storm, much of the forest has been impacted. How will this influence the plant and animal communities within Hawk Ridge Nature Reserve? Perhaps, a BioBlitz may be the best way to investigate this question!

Sunday July 23, saw the second a BioBlitz that has run at Hawk Ridge Nature Reserve in conjunction with the Bog to Ridge BioBlitz supported by Hawk Ridge Bird Observatory and the Friends of Sax-Zim Bog. For those unfamiliar with a bioblitz, the even takes place at one location during a general time frame to find as many species as possible! Now, this may be limited by the expertise of the trip leaders or the participants, but it is a great way to catalog species that can be found in an area. The Hawk Ridge Master Species List (soon to be available online!) is still growing and changing. Lots of information has been gained on birds that migrate through and breed at the Nature Reserve, however, there is very little information on moths, beetles, fungi, bumble bees, spiders, and insects in general. Last year, the BioBlitz added 75 new species including new information on 26 species of lichen! Lichens had not been surveyed from this location, so even the most common species were new to the list. In total, 11 total participants were able to find 159 different species including Ragged-fringed Orchid, Black Bear, and Diamond Spider!

This year, we were able to find 156 different species, including 49 new species for the species list, with 12 total participants: Nearly a mirror image of last year! Just like last year, cloudy and inconsistent weather tried to slow down participation. However, those who did participate were able to add a huge number of species to the master list. Nearly 1/3 of the species observed on Sunday were new to the Master Species List! Big surprises include adding 27(!) new species of plant and 20(!) new species of invertebrate! Exciting invertebrates include Giant Cranefly (Tipula abdominalis), a beautiful species of Orbweaver (Enoplangtha ovata), and a species of bumble bee mimicing Robber Fly (Laphyria sp.)! Another fun surprise for the day included a few neat bird observations like an early flyover by Evening Grosbeaks, Red Crossbills, and tons of Cedar Waxwings! Also noted by the bird group were many of the breeding warbler species at Hawk Ridge Nature Reserve including American Redstart, Ovenbird, Black-throated Green, Mourning, Chestnut-sided, and Nashville Warblers.

A BioBlitz is great event to show folks the diversity of even the most familiar landscapes. Each year, interest in finding and documenting species grows within the general public. Citizen science is as popular as ever and is easier than ever for those interested in reporting sightings. This year, Hawk Ridge Nature Reserve has added a new way for visitors to record the diversity they encounter: iNaturalist!

iNaturalist is a site for the citizen scientist with interest in every piece of the natural world! On iNaturalist, you can document species found in an area with a quick photo and submit these observations to the website for confirmation of ID and is a great way to record any species. Within iNaturalist, you can submit observations on your own, or to projects. Hawk Ridge Nature Reserve BioDiversity is the project where you all can submit your observations of species on your adventures through Hawk Ridge Nature Reserve! This project is looking to record documentations and add to the knowledge of the species diversity at Hawk Ridge Nature Reserve. All you have to do to submit data is make an account on iNaturalist and snap a few photos! You can then upload those photos to the project and share in the understanding of the biodiversity of Hawk Ridge Nature Reserve!

All in all, when we see and observe and document the biodiversity around us, we getting a better understanding of the places and species around us. Hopefully, the interest in the diversity at Hawk Ridge Nature Reserve will extend to your yard and beyond!

February 2017

Dear Friend of Hawk Ridge,

The 2016 fall migration was another record-breaking, thought-provoking season at Hawk Ridge. A total of 415,604 migrants were counted, slightly below 2015’s half-a-million.

Here are some highlights—and some questions. But first, thank you for your membership and support. You’re keeping our eyes on the skies and helping researchers around the world unlock the mysteries of migration—so we can better protect our global natural treasure of hawks and songbirds.

Raptor Highlights

66,369 raptors counted, slightly below the long-term average.

Totals for Sharp-shinned Hawk, Bald Eagle, Merlin, and Peregrine Falcon were greater than any other season since counting began in 1972.

Bald Eagles and Peregrine Falcons continue to rebound from historic lows, demonstrating the effectiveness of targeted conservation efforts.

Merlins are increasing as they adapt to nesting in more urban areas.

The Sharp-shinned Hawk count is especially good news, since this species has been in long-term decline. Typically Hawk Ridge has only one day each season with over 1,000 Sharpies. This fall there were six such days with a peak of 1,454 on September 20.

Finally a respectable Red-tail total! The season total of 8,867 Red-tailed Hawks is the best season since 2006. Is the long period of low Red-tail numbers over?

Of continued concern, counts of Northern Goshawk, Broad-winged Hawk, Rough-legged Hawk, and American Kestrel were all below average.

What are the reasons for these declines? In the case of Northern Goshawks, it is now well established that invasions no longer happen. As for Broad-winged Hawks, it may be nothing more than weather variables during their peak migration season. Researchers believe the lower numbers of American Kestrels indicate a real decline in population.

Non-raptor Highlights

349,235 non-raptors counted

132 Greater White-fronted Geese, an unprecedented number.

Flocks of American White Pelicans impressively large with a season total of 699.

2016’s non-raptor big surprise—the amazing number of Empidonax flycatchers!  The season total of 394 empids is more than all previous seasons combined.

Crazy numbers again this season for Ruby-crowned and Golden-crowned Kinglets (more than 3,600) and Brown Creeper (173).

Although the number of migrating thrushes heard at night always dwarfs the number actually counted during the day, a record number of more than 1,200 thrushes in the genus Catharus were seen in morning flight fall of 2016.

And the prize goes to the warblers—with a total of 78,297 counted, another season record! October 6, 2016 was the peak day for warblers, when 19,465 were counted. A season total of 27,688 Yellow-rumped Warblers compares to the previous average of only about 3,500!

In the case of all these non-raptor groups of birds, the numbers in recent years are ten times higher than in previous years. These numbers represent very real and recent changes in the migration at Hawk Ridge. What are the reasons for these changes and how long will they last?

Eyes on the Skies

Count Director Karl Bardon has been tirelessly tracking raptors and non-raptors at Hawk Ridge for a decade. In addition, he submits data to the Hawk Migration Association North American and other research groups, files extensive reports for HRBO and its members, and continues to inspire new generations of hawk and songbird counters. Many skilled observers helped him in 2017, including HRBO Counter Alex Lamoreaux, Count Trainee Amy West, Count Interpreter John Richardson, Steve Kolbe, Jan and Larry Kraemer, Kathleen MacAulay, Dave Carman, Stephen Nelson, Russ Edmonds, Allie Pesano, Ian Gardner, Andrew Longtin, Josh Lefever, Joe Beck, Tom Reed, Brian Sullivan, and Jerry Liguori. A round of applause and thanks to all.

As the snow flies this winter season, we hope this Vista from the Ridge is providing happy memories of beautiful fall days on the Ridge in 2016. Stay tuned for new things for our members, like Snapshot from the Ridge, more updates on Facebook (https://www.facebook.com/HawkRidgeDuluth), and exciting plans for Hawk Weekend Festival and upcoming gala in September 2017.

Again, thank you for your support. We simply cannot do this important work without you.

Count summary through September 12th, 2016

Hawk Ridge migration has been very busy the last week. We have now counted over 10,000 raptors and over 100,000 non-raptors for the season so far- but this is just the beginning! Peak numbers of both raptors and non-raptors are still to come. Some of the highlights from the last week are shown below with photographs I took this season.

Osprey in flight- we had a great two day run of 41 and 42 Ospreys on 8 and 9 September 2016

Juvenile Sharp-shinned Hawk in flight. We had some high numbers of Sharpies at the Ridge recently including 1066 on 8 September and 1353 on 10 September. Peak Sharpie flights are usually a 1,000 ore more individuals, so its great to already have two such days this season, with many more Sharpies to come.
Although distant, this photo shows a leucistic Cliff Swallow which was seen during a large flight of  2603 Cliff Swallows on 25 August 2016

Here's a Black-and-white Warbler in flight. We are still getting a good variety of warblers, with over 7,000 individuals and 25 species counted this season. The main push of Yellow-rumps is still coming.
Flock of Cedar Waxwings in flight. The bulk of waxwings have probably already moved through. We have counted 28,866 migrating Cedar Waxwings including a peak of 6651 on 9 September 2016

Common Green Darner in flight. This has been an amazing season for dragonflies, with day after day of big flights, often thousands of individuals. Although green darners are usually the most common species, we often have many other species mixed in as well, and a very large flight estimated at 100,000 individuals on 30 August 2016 was surprisingly not mostly green darners, but meadowhawks and blue darners

My thanks to fellow counters Alex Lamoreaux, Steve Kolbe and Amy West, as well as the very helpful group of volunteers that come so often, including Stephen Nelson, Dave Carman, Jan and Larry Kraemer, Russ Edmonds, John Richardson, Karen Stubenvoll, Kathleen MacAuley, Tom Reed, and Peder Svingen

Count summary August 15-24, 2016

Hawk Ride Bird Observatory began yet another counting season on August 15th. Although I am the only official counter on duty until September 1st, I have had lots of help and input from fellow counters Steve Kolbe and Alex Lamoreaux, as well as a few wonderful volunteers. This is my tenth season counting birds for HRBO, and one of the things that keeps me going is that every year is different as we discover new things about bird migration through Duluth. Migration has started out on the slow side, with what seems to be an endless stretch of beautiful warm summer days. But Common Nighthawk migration has been in full swing, and a nice wave of warblers and other neotropical migrants occurred ahead of the season's first cold front on August 19th. Here are some of the first week's highlights with photos I have taken- enjoy!

Adult Bald Eagle flying over Hawk Ridge with a sucker (identified by Larry Kraemer). This is likely a local eagle, heading toward the nest near Ordean school. Raptor migration has been relatively slow so far this August, with only 232 birds counted through August 23rd, but highlights have been two juvenile Peregrine Falcons on August 23rd and three juvenile Northern Goshawks during the period.
Northern Parula, probably a hatch-year bird, and most likely a confusing fall warbler for many. Note the clean-cut wing-bars, greenish back, white eye-arcs, and hint of gray band between the breast and throat. Warbler migration has been slow some days and excellent other days, with an excellent flight during a rain at sunrise on August 19th (1100 warblers) and a smaller flight during overcast skies and NW winds on August 20th (320 warblers)- both days were dominated by Tennessee and Nashville Warblers as well as the first push of American Redstarts, but 24 species of warblers have already been identified migrating along the shore this fall.
Common Nighthawk migrating in front of the rising moon on August 14th. This has been a great season for nighthawk so far, with about 30,000 counted through August 24th. Most of these have been counted in the evening from the Lester River condo by Steve Kolbe, but some others have occurred during the morning and afternoon from both the shore and the Ridge, including a combined one day count of 12,763 on August 19th.
juvenile Baird's Sandpiper standing on a rock along the shoreline of Lake Superior. Although we do not see a lot of shorebirds during the migration counting at Hawk Ridge, this is the peak season for them, and we do occasionally see individuals and small flocks flying by. The interesting thing is that for most species (especially the ones that prefer muddy habitats, like this Baird's), we only see juveniles migrating through, indicating that the birds quickly learn not to return to this rocky habitat during succeeding migrations.
Olive-sided Flycatcher in flight during the early morning. Note the dark flanks separated by a white center stripe forming an "unbuttoned vest." We only count a few Olive-sideds each season, so they are always a treat to see, and this is the first one I have been able to capture in flight.

Apparent Alder Flycatcher in flight. As I mentioned, every season seems to bring something new that I've never seen before, and this year is no exception. On August 17th I was amazed to watch a morning flight of empidonax flycatchers moving through the trees and even flying overhead on occasion. Although we see a few empids each season, sometimes as many as a dozen in a day, there were more than ten times that many on the 17th, and I had never noticed more than a couple in active morning flight migration before. Among 178 empids counted on August 17th, I felt the majority were Least Flycatchers (110) with a minority of Alder Flycatchers (8) and Yellow-bellied Flycatchers (6), but identifying these little guys is probably one of the major challenges in birding. Many of the empids were photographed flying by or seen perched briefly in the trees, and throughout the morning I only heard Leasts calling.
Here's one of the Yellow-bellied Flycatchers in flight on August 17th. Note the yellowish wash to the underside, especially the yellow throat
We will try to keep everyone updated about the migration as the season progresses- we are hoping for a great fall! Feel free to come join us or stop by to ask what we've been seeing.

Bog to Ridge BioBlitz In Review



Hawk Ridge Nature Reserve BioBlitz compilation at the Outdoor Classroom. (photo by Karen Stubenvoll)
































A BioBlitz is really an incredible thing. It provides a unique opportunity to go out in the field with a professional or enthusiast to learn from them and witness their passion for a particular group of flora or fauna or the natural world. Birders know the feeling all too well, but what of the folks who enjoy lichens, moths, sedges, or dragonflies? Generally, those folks don’t get the same level of community and instead venture into the field solo, learning what they can and perhaps finding a person or two with whom they can share experiences. A BioBlitz offers a bit of community for those folks who themselves are enthusiasts or just hoping to learn something about a group of species that they hold dear. 

July 16th and 17th held host to the Bog to Ridge BioBlitz. This was the 4th year for the Sax-Zim Bog BioBlitz, which partnered this year with Hawk Ridge Bird Observatory to conduct BioBlitzes at two locations: Hawk Ridge Nature Reserve and the Sax-Zim Bog. Though both locations are in the northwoods, the Bog to Ridge BioBlitz offered great chances for field trip participants to get a feel for the entire area; from the bogs and conifers of the Sax-Zim Bog to the upland forests and rock outcroppings of the Hawk Ridge Nature Reserve.

Each year, the BioBlitz turns out more and more participants, of all ages and abilities, to explore and document as many species as possible with 5 or 6 hours. On the first Sax-Zim BioBlitz, there were four participants, which is a stark contrast to the over 50 participants at this year’s two day event. Field trips this year were also a bit different from the standard expert lead explorations afield. The Sax-Zim BioBlitz format involved an expert/enthusiast/professional lead trip to find and learn about a particular group of species, ie birds. However, the Hawk Ridge BioBlitz had a generalist focus, look for anything and everything, giving trip leaders the opportunity to share information and excitement about more than just one collection of species.

Overall, the Bog to Ridge BioBlitz had two focuses. First, the Bog to Ridge BioBlitz hoped to show the public a particular location through the lens of a particular species, so that they may begin to understand and care for their local ecosystems. Second, the Bog to Ridge BioBlitz had a goal of data collection. By connecting the public with the task of data collection, it gives greater stakeholder value to the true diversity of a place. Last, by educating the public about a under observed species, it is hopeful that they will, in turn, educate someone they may know and build greater appreciation for a given species or area.

This year, the Bog to Ridge BioBlitz was lucky enough to have a team of 9 experts lead field trips during the course of the two day event. At the Sax-Zim Bog BioBlitz Jim Lind and Dave Grosseuch lead a trip looking for dragonflies and damselflies; Sparky Stensaas and Ben Yokel lead a trip focused on birds; Clinton Nienhaus lead a field trip documenting fish species; Chad Heins lead a group looking for spiders; Jerry McCormick lead a trip looking for Butterflies; and Kelly O’Brien lead a trip documenting plants. Clinton and Sparky also lead trips at Hawk Ridge Nature Reserve, along with Bill Tefft. Each trip leader went out in the field to document species and to educate one of the over 50 field trip participants.
Numbers of species can often be telling of the diversity of an area, however, we cannot always give each species the credit (observation or documentation wise) that it is due. For example, this year during the Sax-Zim BioBlitz 90 new species were added to the already towering species list. In the 90 new species, 20 were moths, 17 were spiders, and 14 were grasses or sedges. Good numbers of new species are great, but there were some astounding records made by Spider Field Trip Leader, Chad Heins. Of the 17 species of new spider added to the Sax-Zim Bog species list, 10 had never been recorded in St. Louis county and 2 species had never been recorded in the state!! As equally exciting as the new records are, all of the spiders found by Chad’s field trip were found within close proximity to the Friend’s of Sax-Zim Bog’s Welcome Center!

The Hawk Ridge Nature Reserve BioBlitz proved equally fruitful, locating 75 new species to the Hawk Ridge Nature Reserve species list including a whopping 26 new species of lichens and plants, and 17 new species of insect. The most impressive point to this list is the amount of new plant species observed. Hawk Ridge Nature Reserve had previously undergone a fairly intensive plant survey, yielding thorough documentation of the area. However, species like Ragged-fringed Orchid, Narrow-leaved Cowwheat, and Wild Geranium had slipped past surveys and avoided previous documentation. All in all, Sax-Zim Bog field trips found 374 species and Hawk Ridge Nature Reserve field trips found 159 species, for a grand total of 424 different species over the two locations!

Each BioBlitz that is done sheds new light to each location, no matter how well we may know its secrets. Case in point, the Sax-Zim Bog master species list was nearly 800 species and field trips were still able to add 90 new species!! What an amazing show of diversity in a location that has had strong documentation. Hawk Ridge Nature Reserve had an impressive list of over 450 species and added 75 new species under the premise of a general species hike. At each of these locations there are certainly more species to be found. Documentation of those lesser known or hard to observe critters like insects, salamanders, moths, and aquatic invertebrates may add much to our already deep understanding of the northwoods. Who knows how fast the species lists can grow if more experts and more field trips are out exploring our local wild spaces?!

Thank you to all that participated, field trip leaders (Jim Lind, Dave Grosshuesch, Sparky Stensaas, Ben Yokel, Clinton Nienhaus, Chad Heins, Jerry McCormick, Kelly O’Brien, & Bill Tefft), Larry Weber for his wonderful evening program, and to the species that let us enjoy and appreciate them. We hope you can join us for another BioBlitz in the future!

Peregrine Watch 2016 Review

The Ups and Downs of a Nest Watch

Peregrine Watch has been a seasonal stop for tourists and locals alike along Duluth's Lake Walk. Each season is different, but in most years peregrine falcons nest in the nest box on the Greysolon Plaza Building in downtown Duluth. Every season is different and this summer was a stark contrast to drama of last summer's observation season!

and the peregrine falcon nest box on the near left corner of the building.

The history of last year's drama begins in 2003, the first year the "Pale Male" (a non-banded bird, who was quite a bit paler than most of our "Eastern" peregrine falcons) nested in the Greysolon Plaza Building's nest box. He was the dominant male bird who used the box consistently, albeit with different females, up until last summer. His mate, "Canada," was paired with him the previous few years, but last year she decided to leave the "Pale Male" and nest on the Torrey Building with "Cloquet," a male who is far younger than she and the "Pale Male." Through Peregrine Watch last summer, folks got to hear and see the story of this drama unfold. The "Pale Male" was seen at the nest box on the Greysolon Plaza Building daily, bringing food to an empty box and to no female. Occasionally, "Canada" who mind you, was nesting on the Torrey Building with "Cloquet", would come and receive food from the lonely "Pale Male." It perhaps was discouraging to listen to the "Pale Male" call for the female on a regular basis, all the while a nest with chicks was out of the question for the Greysolon Plaza Building. But that is nature at it's finest; ups and downs are all a part of the story.

"Cloquet" is the new male in town! Here he is keeping watch
over the city from one of his many perches.

Move the story forward to this summer. During the month of May, "Canada" and "Cloquet" were seen at the Torrey Building, though the nest box was taken down. Perhaps they would attempt to nest atop the building itself? The Greysolon Plaza Building nest box was mostly unattended, sans a non-banded bird (not the "Pale Male") and another banded female. Moving closer to the start of Peregrine Watch, it seemed there would be no birds nesting in the Greysolon Plaza Building box. There was a scramble to watch the box for any sign of action, whether it would be to simply find one bird on/in the box, or see two birds on the Greysolon Plaza Building. Before June hit, it was learned that "Canada" and "Cloquet" had been using the box the entire time we were checking on the box! Moreover, they had laid a total of four eggs!! What news!

Traditionally, Peregrine Watch begins close to hatch day for the peregrine falcon's eggs, that is, the beginning of June or last week of May. This season, Peregrine Watch began on the 2nd of June and the chicks were banded on June 8th. If you look at this timeline and consider that peregrine falcons are generally banded when they are around 20-24 days of age, you can extrapolate that sometime in mid-May the eggs hatched! What a sneaky pair of birds! They had nested right under our watchful eyes, and we missed the whole process of courtship and nesting. The unexpected is why you do a nest watch and educate the public on these wonderful avian predators.

Broad-winged and Red-tailed Hawks, Turkey Vultures, and Herring Gulls that
happened to get too close to the nest!

Each season is different on the Greysolon Plaza Building. I mentioned that the Greysolon Plaza pair of falcons laid four eggs, however, only three of the eggs hatched. Peregrine falcons don't start incubating until the third egg of a clutch has been laid, so loosing one egg usually means harsh conditions at the outset of nesting. Near the start of egg laying by "Canada," Duluth experienced cold and bleak weather, perhaps the driving factor behind the egg loss. With that loss, three healthy male Peregrine Falcon chicks were banded by Amy Ries of the Raptor Resource Project. The Raptor Resource Project manages Peregrine Falcon nest boxes along the Mississippi River and are based in Decorah, Iowa. Raptor Resource Project is also responsible for putting the nest box up on the Greysolon Building in 1992.

Plaza Building nest box.

The chicks were banded with standard grey federal bird bands and blue and black project bands with letters over numbers, for easy identification in the field by biologists or Peregrine Watchers. These chicks were also given names, just a nice way to honor important folks or to keep birds straight when interacting with visitors. The Greysolon Plaza Building chicks were banded with black over blue bands in the sequence of B/51, 52, and 53. B/51 is better known as Bob after Bob Anderson who was instrumental in peregrine falcon recovery in the Midwest and further afield; B/52 was given the name Dudley, after Dudley Edmondson, who, not only is a Duluthian and nature photographer/videographer, but first suggested there be a box placed on the Greysolon Plaza Building; and finally, B/53 was given the name Tristin, after a young man present at the banding.

Peregrine Watch ended on June 30, but not before the chicks had their first flights. By June 23 it was apparent that the chicks were a little older than we had estimated. They had grown in leaps and bounds through the observation in June and were very actively testing their wings, perhaps for a first flight by Saturday, June 25. During the hourly practicing, we noticed that not all of the chicks were seen. "Cloquet" caught a pigeon, and promptly handed it off to "Canada" who went off to feed the chicks. This feeding activity only produced two loud and flapping chicks, not the expected three. By the end of the day on June 30, B/52 and B/53 were both seen actively flying, with no sign of B/51. Perhaps he fledged successfully and was perched atop a different building that could not be seen from Lake Park Place. Perhaps he didn't make it, as the smallest chick in the nest.

are beautiful at every stage of life, whether they are white and puffy
or soaring and stooping with grace and power.

  Success still came from this short season, even with a potential chick lost. Two strong flying, young male peregrine falcons fledged and are a wonderful addition to the skies above Duluth. Even better, we at Hawk Ridge Bird Observatory got the chance to introduce those birds to the diverse audiences that visit Peregrine Watch this and every season. Considering the pinch for time at the beginning of the season, Peregrine Watch was able to be staffed by myself, Eliza Grames, and Miranda Durbin, with volunteer help from Scott Palacheck. We staffed Lake Park Place 12 days, with three cancellations due to rain. We interacted with a total of 885 visitors, averaging about 74 visitors in our 10:00 am- 2:00 pm viewing hours.

Sometimes birds behave as you hope, sometimes they nest in secret, and sometimes they leave to the other side of town for a new male! Every year of a nest watch has new and exciting opportunities for learning, seeing a familiar avian face, or for the unaware, gaining a deeper appreciation for what is directly above us if only we take a chance to look up.

a bit ragged during his post-breeding molt. Or perhaps he was worn
out by his chicks!

Thanks to everyone who stopped out to Peregrine Watch this summer and we hope to see you next summer!
