It was a cool morning in the marsh. These are signs of colder days I am afraid. With the colder weather comes other great birds, so I will look forward to that. The highlights for the day should tell you what a day it was! These include a Scarlet Tanager, Yellow-throated Vireo, Yellow-bellied Sapsucker, and another Connecticut Warbler. Take a look at this bird! A beautiful sight! A nice hooked bill to attack a few caterpillars!
One hundred sixty birds new banded and a bazillion recaptures—only 88, but who is counting! I guess the birds like it here. Most of the recaptures were Blackpoll Warblers and thrushes. Since the birds have been low on fat reserves it makes sense to stay around a while to fatten up before leaving. If the food is good why leave?Eighteen species of warbler were seen today including Tennessee, Nashville, quiz bird, Chestnut-sided, Magnolia, Cape May, Black-throated Blue, Myrtle, Black-throated Green, Blackburnian!, Western Palm, Bay-breasted, Blackpoll, Black-and-White, American Redstart, Ovenbird, Connecticut, and Common Yellowthroat. This is not a bad day! Just in case you did not believe that we caught another Connecticut Warbler... This is a picture taken today!
The Scarlet Tanager was an adult male. See its black wings? They are all black including the primary coverts. No brown primary coverts like a hatching year bird would have.
Another highlight was this quiz bird: See its diagnostic green triangle on its back. For those of you that are color blind, you should still see the triangle on its back.
Blackpoll Warbler-17
American Redstart-2
Main Inside top species:
Blackpoll Warbler-41
Swainson’s Thrush-16
Gray-cheeked Thrush-12
American Redstart-7
Black-throated Blue Warbler-7
Ovenbird-6---plus a couple very fat Ovenbirds recaptured!
Here is the lateral view of the quiz bird does this help?!
I call this bird the butterfly of the bird world because of all of its colors. It is an adult male and boy will he look sharp come spring time! This is a Northern Parula. Did you know they had a two colored beak? Hmmm...
Tomorrow should be good so I hope you can get outside to rack up the fall warbler species! There were some Rose-breasted Grosbeaks around but we did not get to see them up close and personal today. They are still nice to see and know they are here.
We still have not seen any Hermit Thrushes. However, they have them up north so they are on their way. The bird above is a Western Palm Warbler so memorize it because someday it will be a quiz bird!
And this bird is for your Tracy! Everyone likes the fall plumage of a Chestnut-sided Warbler!
Tomorrow’s forecast is for a continued strong westerly wind. Hopefully it dies down some but I do not have hope for that. The rest of the week looks like good winds for more migrants to appear.
And just because I like this bird! This is the first adult male American Redstart for the season. Enjoy!
Blackpoll Warbler on left with yellow pads to its feet and Bay-breasted Warbler with its gray legs and feet. Note the Blackpoll has fine gray streaks on its flanks unlike the Bay-breasted Warbler. That is the key for me to tell them apart in the fall. Use whatever field mark works for you. It may be something totally different.
This is the second fall season for us to catch a Kentucky Warbler. A nice male don’t you agree?!
What about this for a foursome! There are two vireos with wingbars and two without. Can you name them?
There is the accented yellow spectacle on the White-eyed Vireo. Because it is a hatching year bird with dark eyes, the yellow stands out more. It is such a beautiful sight to see the vibrant yellow on the Philadelphia Vireo’s throat and breast. To catch nine Blue-headed Vireos is a prize for the day. The Red-eyed Vireo is also a hatching year bird with a dark eye.
Tomorrow may be a good day too! I am hoping!
Notice the dark black streaks on its upper tail coverts which is a characterstic of male Blackpolls and the adult shaped rectrices-nice and rounded -not pointed like a hatching year bird would be.
Highlights for the day were the grosbeaks and the Red-headed Woodpecker flyovers. Banding highlight includes a nice adult male Cape May Warbler. He is not bad looking for a fall plumaged warbler in my opinion. He has large white wing bars and a pretty well defined facial markings.
A nice looking female Connecticut Warbler! I believe we caught one of these because Sam Woods left the states today! He is still in search of this Bird! How about a quiz bird for the second highlight? It is not a tough one. Look at the beautiful rusty wings and its long tail
And here is the whole bird.
Maybe on Friday we may see the wind come from the northwest so I will keep my fingers crossed. Enjoy the last day of Summer! As a special treat I like the photo of the head of the Yellow-billed Cuckoo!
ENJOY!
and here is the front view of the quiz bird:
Why don’t we just celebrate the good things! How about this female kinglet!
And of course who cannot smile when you see a Winter Wren zipping past you?! Its short little tail and dark undertail coverts separates itself from its cousin the House Wren.
Another treat was this hatching year male Rose-breasted Grosbeak. He tries to look female-like but once you catch a glimpse of his wingpits. The bird cannot be confused with a female Rose-breasted Grosbeak. She would have orange sherbet colored wingpits. The adult male Rose-breasted Grosbeak has black flight feathers and more rose on the breast.
Rain is forecasted for tomorrow and scattered through Thursday. If there is a break in the weather the birds will be out feeding. Take time to enjoy summer before it ends on Tuesday! We captured a Brown Creeper on 09-19-09 (yesterday) so maybe winter is around the corner!

It could look like a female like Common Yellowthroat but the bill is much larger similar to what an Oporornis would have. That is your hint. The eye markings may not be as obvious on this bird as some you may see of this species.
This will help you differentiate from the red-backed/red tailed Veery and the brown backed/brown-tailed Gray-cheeked and Swainson’s Thrush.
I want to know why the Swainson's Thrush used to be called the Olive-backed Thrush. It looks like to me the Gray-cheeked should have been called that. Oh well, they did not ask for my opinion.
Notice also that the breast spots on each species is different. Swainson's usually wears vivid breast spots with some buffiness. The Gray-cheeked has vivid spots and no buffy coloration. The Veery has blurry, indistinct spots.


and a nice looking adult male Connecticut Warbler. Yes, you heard me a Connecticut Warbler. So get out there and look for the Connecticut Warbler you missed in the spring. We catch more Connecticuts in the fall than we do in the spring; so maybe your chances of seeing one is greater in the fall.
Below is a Hatching Year (HY) male Mourning Warbler with the adult male Connecticut Warbler. I am hoping you can see the split eye ring on the Mourning Warbler and the Connecticut Warbler's eye ring is more vibrant or as I say goes "boing!" compared to the duller split eye ring of the Mourning Warbler.
Another highlight for the day was this Philadelphia Vireo. Its lemon yellow throat and belly look like lemon meringue pie.
Eight species of warbler were seen or heard today which include Magnolia, Black-throated Blue, Blackburnian, Bay-breasted, Ovenbird, Connecticut, Mourning, and Common Yellowthroat. American Robin, Veery, Swainson’s, and Gray-cheeked Thrush were the thrushes for the day. 
And here is a close-up of the head. It has buffy-white split eye ring so it is a hatching year male. If it was completely white split eye ring it would be an adult female and if it was all buffy with no indication of white in the split eye ring then it would have to go unknown for the sex. Some hatching year males will not show white in the split eye ring. Remember we also look at other characteristics such as alula (thumb) feather shape and other features to determine the age and sex of this quiz bird. So have you guessed the bird yet?
Here is another great fall warbler who has a different plumage in the fall than in the spring. Can you tell what sex this Chestnut-sided Warbler is? Do you notice a small bit of chestnut just under its wing? This makes it a hatching year male. Also once again if it does not have any chestnut on the flanks of a hatching year bird we cannot determine from its physical features if it is a male or female.
A couple highlights of the past couple days were our first Blackpoll Warbler and Gray-cheeked Thrush. A couple more Swainson’s Thrushes have appeared. The two days we banded 36 new birds and 8 recaptures. It looks like the weather is not going to change anytime soon. The days will come when the Blackpoll Warblers and thrushes will be here filling the trees, one just has to be patient. P.S. the quiz bird was a Mourning Warbler!
Answer is at bottom of post.
Another first for the fall which may make you think it is time for winter is this Purple Finch. As you can see it has loose juvenile feathers on the body with characteristic stripes on the flanks, thick beak, and dark facial stripe through the eye (It may be hard to see in this photo). This is a hatching year unknown sex bird. You cannot tell male from female at this stage in a hatching year Purple Finch's life. It is safer to look like female-like if you are a young male Purple Finch than to be bright purple and have the adult males showing aggression towards you. Its life may have a few less complications and add to its survival.
Another bluebird day forecasted for tomorrow. The weather is not supposed to change until sometime on Monday. However, there have been at least nine species of warbler seen around the marshes today ( Nashville, Magnolia, Blackburnian (no, I have not seen one yet), Bay-breasted, American Redstart, Ovenbird, Northern Waterthrush, Mourning, Common Yellowthroat). Who knows you may see one that is not listed.
Despite small numbers, there was an opportunity to see identifying features of a hatching year Ovenbird and Northern Waterthrush. Looking at the tertials, you can see the Ovenbird has rusty edged tertials and the Northern Waterthrush has buffy or tan edged tertials. This is the identifying age characteristic for these species.
And if that does not help, how about whole bird!
Such a beautiful bird! The Marsh Wren rarely comes out of the marsh but it did today! Enjoy the day!
