Three-year old female PROW back at Northwest River

Guest blogger and CVWO Volunteer Shirley Devan back with an update from the Prothonotary Warbler nest box trail at Northwest Rive Park in Chesapeake, VA.

Recaptured Prothonotary Warblers continue to tell interesting stories about the life history of these migratory birds.

July 6, I recaptured two female PROWs.

At box 37, the female with 4 eggs was originally banded as a NESTLING June 22, 2009 in box 36 right next door! She has made 4 round trips between Virginia and her wintering grounds in Central or South America.

At box 39, the female with one egg in her nest was originally banded by Steve Living May 16, 2012 at the SAME box with 4 eggs. Her four nestlings were banded May 29. She will likely lay 2-3 more eggs in this second clutch.

The first male PROW captured at Northwest River in 2012 was at Box 11. Photo attached! Always a treat to capture a beautiful male PROW.

We will continue monitoring through the end of July because second clutches are well underway with females still laying eggs the first week of July.

So far Steve Living and I have banded over 150 nestlings and two dozen “new” female PROWs. See previous posts for more 2012 information about this project.

Second Clutches Underway for PROWs at Northwest River

By Shirley Devan, Volunteer, Coastal Virginia Wildlife Observatory

We are checking the Prothonotary Warbler nest boxes every week down in Chesapeake at Northwest River Park. These days we're finding lots of second clutches.

But sometimes we find other wildlife…like a Black Rat Snake in one box a couple of weeks ago. Now that's a surprise. Unfortunately, the snake had eaten PROW nestlings. Subsequently we repositioned that box.

The PROW nestlings are only in the box for 10 days before they fledge. Steve Living and I have a short window to band nestlings, who should be 5 grams or 5 days old when banded.

We've banded over 100 nestlings so far and trapped over 30 females, four of which were banded as adults in 2009! At least four migratory round trips for these ladies.

2012 at Northwest River Park

By Shirley Devan, CVWO Volunteer.

[Brian Taber has invited me again this year to post info about the Prothonotary Warbler project at Northwest River Park in Chesapeake.]

Prothonotary Warblers continue to show strong fidelity to the nesting habitat at Northwest River Park in Chesapeake, VA.

Under the supervision of Dr. Bob Reilly, CVWO’s Master Bander, Steve Living and I are monitoring these cavity-nesting birds again this year. This is one of the songbird research projects sponsored by CVWO.

Steve Living is a Terrestrial Biologist with the VA Department of Game and Inland Fisheries. I am a CVWO volunteer, Certified VA Master Naturalist and avid birder in Williamsburg Bird Club. Both of us are licensed to band songbirds as subpermittees working under Dr. Bob Reilly. Each of us relies on volunteers to help with the project.

After the 2011 nesting season, Bob Reilly repositioned over 20 of the 100 boxes to more suitable habitat.

We observed the first PROW eggs April 24 and banded the first nestlings May 16. As of May 22, 18 PROW nestlings have been banded and at least 55 of the 98 boxes have nest activity. We’ll be monitoring these boxes through mid-June at least and expect that we’ll band in excess of the 133 nestlings we banded last year. Prothonotary Warblers often have two clutches in one season.

The first females were trapped May 10. So far we have banded 13 adult females. We have “recaptured” 11 adult females [banded in previous years], four of whom were banded as adults in 2009, one was banded as an adult in 2010, and four were banded as adults in 2011.

Here is a photo of a nestling on the scales! He’s ambitious – trying out his wings already!

Mississippi Kite at College Creek Hawkwatch

Fred Blystone and I watched as this adult Mississippi Kite, our first of the season, flew across the river low and right overhead! As is typical, because we are looking south, the bird was backlit, so the photo shows little detail besides the distinctive profile.

Spring Bird Count

The Williamsburg Bird Club held its annual spring bird count on April 29. These American White Pelicans were present on the Hog Island Sector in Surry County ... one displayed the unusual breeding bill plate. American White Pelicans have been seen there since April 4. As a special bonus, this frisky mink also scampered past.

1,000th Bird at College Creek Hawkwatch

Today we recorded our 1,000 bird of the season...a milestone we like to track to see how the season is progressing, compared to other years. Last year, our record season total was 1811 and we reached our 1,000th bird on the record early date of March 20th. It's usually in early-to-mid April, so this year is very late.

As a bonus, today, though, we again saw a flock of 20+ American White Pelicans...and our first Least Tern flew low right over our heads!

More American White Pelicans!

This very high flock of 21 American White Pelicans is one of several groups seen over Hog Island WMA and College Creek Hawkwatch, over the past couple of weeks, including a new State high of 33...photo by Bill Williams.

Harvester

Very rarely seen in Virginia, this Harvester was in my yard today in James City County. Its caterpillar is the only carnivorous one in North America, feeding on woolly aphids on greenbriar and beech, among other plants. The adult butterfly doesn't nectar on flowers, but instead feeds on aphid honeydew, dung, sap and mud.

American White Pelicans!

Very exciting this week were 24 American White Pelicans on April 4th and 11 today, seen from College Creek Hawkwatch. The previous local high count was 8, as they are very rare here, mostly seen from the hawkwatch over the years.

Prothonotary Warbler Program

Prothonotary Warblers are due back any day from their winter stays in the tropics...volunteers Adrienne Frank, Gary Driscole and I paddled the pristine Dragon Run river today to repair and clean out nest boxes, which are placed over the water. Warbler progress will be monitored throughout the nesting season. The program is a partnership with Friends of Dragon Run and is part of a large Virginia network of hundreds of boxes.

First Landing Songbird Station

Our First Landing State Park (Virginia Beach) Songbird Banding Station opened at the beginning of March and will run daily, weather permitting, through May. There will be regular updates on our website's First Landing Blog, but I thought I would also show some pictures of a visit there today. Calvin Brennan is our head bander and Ashley Kuflewski is our intern. Here, they are checking mist nets and processing an adult male Dark-eyed Junco.

Tundra Swans

Tundra Swans come through in early March at College Creek Hawkwatch, sometimes by the hundreds, always a gorgeous sight...these 3 today were lower and closer than the usual high-altitude flocks.

Hunting Red-tailed

This Red-tailed Hawk at College Creek Hawkwatch today, likely the one from Feb 10 posted earlier, apparently had a small mammal underfoot, as it listened, jumped and stomped around for several minutes in a small marsh after last night's light snow.

College Creek Hawkwatch Begins

The 16th consecutive late winter/spring hawkwatch at College Creek began today. It's the only regular hawkwatch in VA during this season. It was very hazy today, as the photo shows, unusual for this time of year, but southwest winds and temperatures in the 40s made for a pleasant start. Two birds were tallied coming across the 1 1/2 mile wide James River, a Turkey Vulture and a Red-tailed Hawk. The Red-tailed pictured above was not seen migrating, but welcomed me to the site, atop the only cedar tree there.

The hawkwatch operates daily, weather and schedules permitting, with several volunteers through May. It is generally a morning event, from about 9-1, as birds use the warming air to cross the river. Many other migrants are seen, including swallows, waterfowl and shorebirds. Visitors are always welcome, contact me for other details as needed. It's located on the Colonial Parkway, about 3 miles south of Williamsburg. Information will be regularly posted here, on the VA List Serve and on our Facebook page.

Snowy Owl!

A Snowy Owl was reported today from the Chesapeake Bay Bridge-tunnel...and a photo was forwarded to the Observatory's Facebook page. There have been a number of widespread reports of Snowys in the east in recent weeks.

Final Results for Prothonotary Warbler Boxes in Chesapeake, VA

Shirley Devan here again. Blog Owner Brian Taber invited me to post the final results of the Prothonotary Warbler nest boxes at Northwest River Park in Chesapeake. We had a great season down there. Here are the final data.

Stephen Living, VaDGIF Wildlife Biologiest, or I, plus volunteers from CVWO, Williamsburg Bird Club, and Historic Rivers Chapter of VA Master Naturalists, visited Northwest River Park 22 times between April 13 and July 5 – sometimes twice a week – to ensure that as many nestlings and adults as possible were counted and banded. Here are the final numbers:

• 136 PROW nestlings banded
• 17 new PROW females captured and banded
• 3 new PROW males captured and banded
• 55 boxes showed evidence of PROW nest activity (from "sprig of moss" to 2 broods)
• 6 boxes had 2 broods that were banded
• 9 female PROW females banded at Northwest River in 2009 and 2010 were “recaptured” in 2011. Five were banded as adults in 2009; one was banded as a nestling in 2009; three were banded as adults in 2010.

In the original 39 boxes at Northwest River Park since 2008, 38 boxes showed evidence of PROW nesting activity – ranging from “sprig of moss” to two broods.

Many thanks to the organizations who provided start-up supplies, labor, and financial support for this 2011 effort:

• Coastal Virginia Wildlife Observatory
• VA Department of Game and Inland Fisheries
• Virginia Society of Ornithology
• Richmond Audubon Society
• Williamsburg Bird Club and individual Bird Club members
• Members of Historic Rivers Chapter, VA Master Naturalist

The 62 new boxes installed in 2011 showed moderate to no activity, depending on location. Ten of the 23 boxes close to the original 39 hosted PROW nest activity. The farther the boxes were from the original 39, the less activity. Some of the boxes will be candidates for repositioning in 2012, but many will probably remain in position for a second year to give the warblers a chance to find and nest in them.

We’re looking forward to mid-April 2012 when the first Prothonotary Warblers arrive!! Stay tuned.

Golden Eagle at Kiptopeke

This hatch-year Golden Eagle today at the Kiptopeke Hawkwatch was the 2nd for the season.
