Red-shouldered Hawk Banding

Print Friendly and PDF

June 6 was a beautiful day to spend outdoors learning about the state -threatened red-shouldered hawk and helping band young red-shoulders. We were very fortunate to have Wisconsin’s red-shouldered experts, the Jacob brothers, Gene and John, come to the red-shouldered hotspot in Columbia County to band young. http://www.raptorresearch.com/ and  https://raptorservices.rezgo.com/

The goal was to remove the chicks from the nest, place them safely in a cloth bag, and lower them down for banding and taking scientific measurements, and return them back to the nest.

Team members joining the Jacob brothers included Mark Martin, Graham Steinhauer, and Tanner Pettit (summer intern) from Goose Pond Sanctuary; Goose Pond volunteers Arlene Koziol, Brand Smith, and Bob Bennicoff; MAS board members and photographers David Rihn and Pat Eagan; local resident Cole Hollander; and Savanna Grayless from the DNR Columbia County Wildlife staff.

We began at the first nest located 53 feet high up in a shagbark hickory tree located 20 feet from the front porch of a home in the Wisconsin River forested floodplain of Portage. The brothers are very safety-oriented and spent some time analyzing how to approach the nest.  A 10-foot vine of poison ivy on the tree truck presented a challenge, however they had a 12-foot long ladder that could help them get them above the ivy.  The thick and shaggy bark also presented a challenge for climbing up the trunk. They decided to not climb the trunk but climb a rope if they could propel and position the rope over a limb about four feet over the nest.

They assembled their fancy device, a seven-foot long slingshot, and skillfully shot a thin lead rope over the desired limb on the first try, an activity that can sometimes takes an hour to get into place.

While getting a larger rope safely secured Mark asked which of the young team members was going to climb.  John, the older brother and the oldest of everyone present, brought a smile to three of the four younger people when he said that he would climb this nest.  This was John’s first climb of the year.  Everyone was impressed and learned that it takes a strong person and someone not afraid of heights to make the climb. 

John was exhausted when he reached the nest and very disappointed that he could not reach the young and get in a better position. While at the nest an adult brought in food for the young and after noticing John began swooped around. John was wearing a hard hat but luckily the adult did not hit him.

It took John about one minute to descend compared to many minutes to pull himself up the rope. He stated that he was done climbing for the day.

Before lunch Gene suggested that the rope be left in place in case the second nest was not active. John stayed behind to rest and eat his picnic lunch on the front porch.

After lunch we headed to the next location about 1/3 mile away.  This nest was in a swamp white oak 47 feet from the ground and about 30 feet from buildings. Team members were helping get the safety ropes in place when someone spotted a fledgling hawk in the water below the nest. Only its head and part of one wing was not submerged. We all thought the young bird was close to death, however Brand Smith quickly called the Four Lakes Wildlife Center in Madison to see if we could bring it to them for care.

The bird was dried off and placed on a towel in the sun to recover. On close examination by John, he found the crop almost full and thought that the bird would survive without assistance. It was exciting to see the chick recover, move its wings and start chirping. John banded the bird and the young male was ready to return to the nest.

Gene harnessed up and ascended the tree, negotiating a number of limbs as he climbed. Only one young hawk was present in the nest and it was lowered down to the team who banded the bird and Gene placed both safely back into the nest.

Back at the first nest, John and Graham had been talking and John asked Graham if he would like to make the climb. Graham was waiting for John to ask him! Graham has climbing experience and with coaching from John, it did not take him long to reach the nest. He was also in a good position at the nest and three young were lowered to the ground, banded, and safely returned to the nest. Graham was pumped to be able to help out and John hopes that he will become a “raptor climber.”

Additional information:

  • The banding data is used by the Bird Banding Laboratory. From their website: the Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the status and trends of bird populations are critical for identifying and understanding many ecological issues and for developing effective science, management and conservation practices.

  • The Jacob brothers began studying raptors in the early 1970’s. Madison Audubon Society is helping fund their red-shoulder research that includes attaching transmitters to study migration, home ranges, and learn about the ecology of these forest raptors. John’s red-shouldered study area is in northeast Wisconsin and Gene’s study area is in central Wisconsin near Stevens Point. Note that Gene bands saw-whet owls in October at Linwood Spring Research Station. The station is open for visitors by reservation.

  • DNR conducted red-shouldered surveys using calls from 2010 to 2012, however there were no survey routes in Columbia County.  Most of the surveys were along floodplain forest river systems like the Lower Wisconsin, Black River, Wolf, and Chippewa Rivers. The first year volunteers found 110 red-shoulders on 23 routes.

  • On the first Breeding Bird Atlas in Columbia County only one pair of red-shouldered hawks was found and listed as “probably breeding.” Back then, we did not know how to locate red-shoulders.

  • This year we decided to conduct special red-shouldered surveys for the Breeding Bird Atlas II, and Brand Smith took the lead with assistance from Mark, Sue, Graham, Bob Bennicoff, Dory Owen, JD Arnston, Bill Smith, Jane Furchgott, Nydia Klien, and Richard Staffen. Everyone has good memories of the survey days. One day team members were out and Brand and others located the first nest that we banded at. After that, some team members changed teams.  Dory was with Brand and ask what the plan was. Brand stated “we should be on the lookout for nests.” Within one minute Dory exclaimed, “There is a nest!” This was the second red-shouldered nest we banded at. Jane, Bill, and Rich surveyed the Baraboo River floodplain forest where the Baraboo enters the Wisconsin River. Their highlight was finding 10 red-shoulders and three nests.  Brand also confirmed nesting when he observed a red-shoulder carrying a frog to a nest. The Jacob brothers mentioned that frogs are a major prey item. Another day, Brand and Bob really enjoyed canoeing a mile on a road near the Wisconsin River with water four-foot deep in some areas.

  • Thanks to the hard work of our atlas team we confirmed eight nests in six atlas blocks over 14 river miles and wonder how many nests were missed? Atlas volunteers have only confirmed four nests in 92 miles of Lower Wisconsin River.  

THANK YOU to Gene, John, and Graham and team members for making this a memorable day, to everyone who helped locate red-shoulders, and to the landowners for allowing us to band the young.

Eastern Kingbird

Print Friendly and PDF

The Eastern Kingbird, a delightful bird to watch on June mornings, marks open areas with its broad tail feathers, notched at the bottom with white. To watch a kingbird is to see a bird puppeted about as it moves from a snag, hawks a group of insects, and returns to that same perch. Last year I witnessed the delightful presence of recently fledged kingbirds on a power line along North Shore Road. The parent bird went one by one and delivered food to each fledgling—a precise and delicate process.

Kingbirds can be found in open habitats, from savannas to prairies to orchards, across much of the United States, including all of Wisconsin. Constructing haphazard nests in shrbus and trees, the birds will defend those nests and territories from nearly every intruder. Aggressiveness of breeding birds is a common sight, and dazzling aerial maneuvers often ensue. In flight, the kingbird’s tail will regularly fan out, as the bird hovers, twists, and maneuvers chaotically.

Its Latin name Tyrannus means tyrant or despot, and the kingbird lives up to this with its defense of its nest from brown-headed cowbirds, blue jays, and hawks. You can find kingbirds at Faville Grove in most open habitats with a scattering of trees. Watch for their distinctive white tail tip and kiting flights in grassy areas.

American Kestrels: 2019 adult banding results

American Kestrels: 2019 adult banding results

I am glad that it has warmed up and that it is time to band kestrels! Thirty volunteers for Madison Audubon’s Kestrel Nestbox Monitoring Program were busy in March cleaning out kestrel boxes, and we’re now seeing the results of their work. This nestbox program has two primary goals: 1) provide clean, abundant nest sites for kestrels to raise their young, and 2) create opportunities to band both adults and chicks to study their migration patterns, demographics, nesting preferences, and more.

Chestnut-sided Warbler

The chestnut-sided warbler, decorated as it is with chestnut-streaked flanks, almost resembles an oak leaf. Indeed, in southern Wisconsin the breast of a chestnut-sided warbler could very well extend from a cured black oak leaf—a potential spot for finding this warbler during the breeding season.

I love the appearance of a chestnut-sided warbler: with its yellow cap it declares its warbler-ness while its messy chestnut streak resembles spilled coffee down its side. Likewise endearing is its call—the mnemonic I've come up with is “choo choo choo god-bless-you!” Unlike the eastern towhee which admonishes you to “drink your tea,” or the yellow warbler (which can have a confusingly similar song) in its braggadocios endowment of itself as “sweet, sweet, sweeter than sweet,” the chestnut-sided warbler sneezes and humbly excuses itself.  

There's more to that song than the trivial way a human remembers it, however. Ending the chestnut-sided's song is either an accented or unaccented syllable. When the accent is used, the male is attempting to attract a mate, while the unaccented song is employed for territory defense when other males are around. So, we have some idea of the language of the chestnut-sided warbler: if he's on a nest, you might expect to hear the territorial song (unaccented) while his accented ending may mean he's still looking for a mate.

Further research into chestnut-sided warbler song has revealed that certain songs are associated with greater reproductive success. It turns out, in chestnut-sided warblers, high-pitched and steady wins the race. Males who sing with a high and steady pitch and consistent timing are more likely to have a successful breeding season. If you hear a chestnut-sided warbler in the woods that's mapping new vocal territory with each song, it's not as likely that a female will choose this variable warbler.

When I've encountered chestnut-sided warblers it's been in oak barrens areas in northeastern Wisconsin, where the bird is common north of Marathon County. It's uncommon in central Wisconsin, and a rare breeder in southern Wisconsin where I've seen it in regenerating oak scrub in the southern Kettle Moraine. While this bird's preferred habitat is rather rare in Wisconsin (oak savanna and barrens), the advent of large-scale logging operations proved a great benefit to chestnut-sided warbler populations. These birds will readily occupy cut-over land, and as such they have a secure population in northern Wisconsin.

Sora

Chris Ribic in 2006 wrote in the Atlas of the Breeding Birds of Wisconsin, “Clap your hands in a wetland or slap your canoe paddle on the water in May or June, and you will likely hear the whinny of North America’s most common rail.” 

Ribic also reported that Wisconsin wetland bird researchers “have found that sora occur in higher densities in cat-tail or bulrush marshes compared to sedge/grass meadows.”  We search for them in shallow water areas.

If you are lucky to see this small rail (that weighs less than three ounces) fly, it appears to be a weak flyer and only flies short distances.  But don’t be fooled by this illusion: soras migrate south hundreds of miles to the coastal marshes and central America for the winter. 

The Cornell Lab of Ornithology reports “Their population was stable between 1966 and 2015… they rely on wetland habitat that is dwindling due to urban and agricultural development”.  In Columbia County, we where we are conducting the Breeding Bird Atlas II surveys, we are finding soras in several thousand acres of restored Wetland Reserve Program (WRP) lands.

Columbia County atlasers have been out for the past four nights and are impressed with the number of soras found.  Mark and Brand Smith walked in a large WRP wetland for 1.5 miles from 8:45 p.m. to 10:30 p.m. They stopped seven times and played songs/calls of sora, Virginia rail, least bittern, and American bittern and were rewarded by hearing 22 sora and two American bitterns. Only one sora called before the recording of the call was played. (Click here to read about the “Proper Use of Playback in Birding”.)

Mark and Brand also stopped at two other sites along a road in a sedge meadow and found nine soras and three Virginia rails, all within 100 yards of the stops.

We always thought that the best time for surveying for rails was after sunset and before sunrise. However, we learned that they can also call during the day when Brand was surveying for red-shouldered hawks by playing the hawk call and a sora answered. He then switched to calling rails and had replies from 8 Virginia and 11 soras. Impressive, since he was out in the early afternoon.

Our goal is to search the 18 priority atlas blocks in Columbia County for rails and bitters in the next month. Graham searched all the rail habitat (less than five acres) in the Arlington CE block and was lucky to hear a sora that was calling within 100 yards of the interstate.

Mark and Graham recently conducted a waterfowl count at Goose Pond and flushed four sora rails. On May 16, they conducted a rail count on a beautiful spring night with a lot of frogs and toads calling, and two males responded to the calls. They will survey again in a week and if they hear the rails call, the species will be upgraded to “probably nesting” in the Breeding Bird Atlas II project.

We encourage you to check out “rail” wetlands and see what you can find. Two locations in Jefferson County to explore are Zeloski Marsh (purchased by Madison Audubon and donated to the DNR) and Rose Lake/Dorothy Carnes Park (donated to Jefferson County) near Fort Atkinson. Look for shallow waters with cattails, bullrushes, and marshy habitat. You might get lucky enough to hear that magical whinny.

We are always looking for help with the atlas and welcome rail surveyors (goosep@madisonaudubon.org) or you can help with the DNR survey for Secretive Marsh Birds including rails. There are 13 open routes within Madison Audubon’s chapter boundaries.
