Migration Monitoring – May 22nd, 2007

Pictures have been added to the bottom of this post.

There was a good variety of birds around today with 70 species being recorded on ETs. New for the season were Willow Flycatcher and Philadelphia Vireo. The warm temperatures have encouraged the mosquitoes to come out in number.

Banded: 35
Wilson’s Warbler 1
Tennessee Warbler 1
Magnolia Warbler 3
American Goldfinch 1
Chestnut-Sided Warbler 2
Black-Throated Green Warbler 1
Brewster’s Warbler 1
American Redstart 1
Yellow Warbler 6
Blackpoll Warbler 2
Common Yellowthroat 2
Yellow-Rumped Warbler 1
Traill’s Flycatcher 1 (likely a Willow as there were a few around)

Swainson’s Thrush 2
Baltimore Oriole 1
Grey Catbird 5
American Robin 1

Retrapped: 28
Blue-Grey Gnatcatcher 1

Tree Swallow 1
Indigo Bunting 1
Orchard Oriole 3

One of the Yellow Warblers, banded on August 3rd, 2004, has been handled by 8 banders during its time at Ruthven.

The Indigo Bunting was originally banded as an AHY on August 3rd, 2002, making it at least 6 years old this year.

One of the Baltimore Orioles was banded as a HY bird on August 16th, 2001 and had not been seen since.


A few pictures from the day:

A Chestnut-sided Warbler

An American Redstart (male)

Catching a few Blackpoll Warblers was pretty exciting.

A Brewster’s Warbler. These birds are the result of interbreeding between Blue-winged and Golden-winged Warblers–notice the similarities to the Blue-winged Warbler that is pictured below. The Brewster’s has less extensive yellow coloring, and adult male Brewster’s Warblers can have even more grey coloration on the breast and back than the one pictured here, which I believe we called a second-year female (Brian would have to confirm this, and Rick would have to tell us why this is wrong).

Another shot of the Brewster’s warbler.

A Blue-winged Warbler. This was a retrap, and is likely a breeder at Ruthven.

A young male Cape May Warbler.

A nice looking male Indigo Bunting. This ‘retrap’ may also be a Ruthven breeding bird.

A Magnolia Warbler

One of yesterday’s Philadelphia Vireos. There were several (at least 3) on the property yesterday, and yesterday was the first day they were observed at Ruthven this season.

A Ruby-throated Hummingbird who got tangled in a net yesterday. We don’t band these birds at Ruthven, but are more than happy to take a few pictures of them.

A Tennessee Warbler

A Wilson’s Warbler

A Swainson’s Thrush. It seems I couldn’t get his face in focus, but at least you can get a good look at his chest markings.

One of our younger visitors from earlier in the week dropped off this drawing, which is now posted in the banding lab. I’m not sure who that visitor was though, so maybe he/she could leave a comment on the blog and let us know his/her name.

  1. The picture IS posted in the banding lab. We like art. And cookies too for anyone reading.

  2. That was supposed to say that the picture ‘is NOW posted in the banding lab.’ Sorry about that.
