Bulletin 172 - mid April migrants

It has been rather slow in migration this year for the last 2 weeks.

Here is a Prothonotary Warbler. It is one of my favorites with his intense yellow-orange color and blue gray wings.

Another warbler this weekend was this male Yellow Warbler. He is all yellow, including the wing bars. The male has the reddish streaks on the breast and the female would lack these streaks.

This male Black-throated Green Warbler hung around the drip at LaFitte's Cove. Often, he was so close that I could almost touch him and thus too close for a photo.

A Red-eyed Vireo posed on a stick over the drip after his bath. His head feathers are sticking up from the bath, He normally doesn't have a crested appearance. His red iris is visible in this photo.

Summer Tanagers are among the most strikingly colored birds. This solid red male had a huge mouthful of mulberries.

The females in the eastern USA can be orange to greenish color. This one was very orange with scattered red feathers. She was right above me and so close, I could not get her completely in the photo.

Sibley says in his description of this species, that they can have a slightly crested appearance. Here is the same bird a few frames later sporting her crest.

The male Scarlet Tanager is beyond comprehension with his red body and head and black wings and tail. I always love to see them in spring and always take a photo.

One confusing spring bird is the first year male Orchard Oriole. This greenish-yellow bird has 2 white wing bars and a black throat. It is very different from both adults and for a long time was thought to be a separate species of oriole!

Lastly, a brown bird, the Swainson's Thrush. He is IDed by the plain brown back and large eye ring. He is a rather dull bird after the tanagers. However, all the thrushes are superd singers and if you ever hear him sing, it is wonderful. Here is a link to a You Tube video of one singing by Naturalist97333.

Lastly, this normally long slender Gray Catbird, was all hunched down like a dove. His black cap and rusty undertail are well seen in this view.

Bulletin 170 - early migrants

With the arrival of April, spring migration here is officially underway. However, some early migrants come in March and us hard core birders seek them out.

The Myrtle Warblers are getting yellow crown spots, This was the first time I recall noticing these crown patches.

Myrtle Warbler

Speaking of crown patches, the Orange-crowned Warbler keeps his patch hidden and the only time I have seen it was when one was bathing. I have never seen it otherwise and most birders will tell you it is never seen. Well this bird broke the rule. He kept his orange crown visible as he came to the drip at LaFitte's Cove Galveston last Friday.

Even this Nashville Warbler got in the act and showed the red feathers in his crown patch.

A male Northern Parula came to the drip and posed nicely for a photo.

A surprise bird was this Audubon's Warbler is almost full breeding plumage. This is the western form of Yellow-rumped Warbler and differs from the Myrtle Warbler above by having the yellow throat.

A couple of early Black-throated Green Warblers were found as well.

I was very pleased to find one of my nemesis birds, the Yellow-throated Warbler. This is only the third time in my life to see this common bird.

The Black-and-white Warbler is a favorite of mine. They work the trunks and larger limbs of trees in a style like a nuthatch.

The Louisiana Waterthrush is the earlier of the waterthrushes to arrive. It is IDed by the long eye stripe going down the back of the neck as well as pink legs and buffy flanks.

An unusual find was a Calliope Hummingbird at LaFitte's Cove the last few weeks. This bird at 3.25" in length is the smallest North American bird. This was a juvenile male. My first photo on March 23, shows a few red throat feathers on the right side.

By the next week, he had sprouted almost a full throat of feathers.

I am looking forward to many more migrants coming through over the next month. I hope everyone can get out to see some of these birds as they pass through.

Bulletin 164 - Fall/winter birds

I hope everyone had a wonderful Thanksgiving last weekend.

The majority of the fall migrants have passed through. However, a number of warbler species do winter over in limited numbers, according to the Checklist of Birds of the Upper Texas Coast.

The common winter resident warblers are Myrtle, Orange-crowned and Pine. So it is always fun to find some other species that are either very late migrants, or birds that have decided to go no further south.

Here is an Ovenbird that I found by the drip at LaFitte's Cove in Galveston on Oct 26th.

And here is a Black-throated Green Warbler from Thanksgiving weekend.

This beautiful female Summer Tanager was also seen on Oct 26. According to the checklist, a few of this species also winter over here.

That same day also produced my first pair Lark Sparrows at LaFitte's Cove in Galveston. The distinctive facial pattern make this sparrow an easy ID.

The White-tailed Kite (Elanus leucurus) is a beautiful all white raptor with black shoulder patches. I had been told about a pair of these birds nesting along Stewart Road in Galveston in a dead tree. It was difficult to get any photos of the birds on the nest as they sat very low down in the nest. Last weekend, the 3 babies had fledged. the family group of 5 birds were in the tree and 2 were on the wires beside the road. I stopped my car and took photos out of the car window. Using the car as a blind in this fashion doesn't disturb the birds like getting out of the car would.

Here is one of the adults. It is all white with a gray back and black shoulder patches.

White-tailed Kite - adult

This was the first time that I had seen and photographed the juvenile plumage. They are washed on the head, breast and back with reddish brown.

White-tailed Kite - juvenile

Later I found another juvenile eating lunch on top of a post. The diet of these birds is insects and small rodents. Also notice on these juveniles, that the wing feathers are all edged in white.

Now, what about that quiz bird form the last bulletin. Here it is again, a Yellow-throated Vireo.

Yellow-throated Vireo

The question was a missing field mark and why. I had a few people makes some guesses, but no one got the answer as to what was missing.

Here is a photo of another vireo.

Warbling Vireo

The field mark that isn't visible is the hook on the upper mandible. The beak is the differenting field mark of vireos from warblers. Warblers have thinner straight beaks. The vireos have thicker beaks and the upper mandible is hooked at the end.

Notice in the photo that the upper mandible of the quiz bird doesn't reach to the end of the lower mandible and the hook is not visible.

Why? I think the bird has a beak deformity. Here is a photo of the same bird head on and you can see the upper mandible is bent to the right. The hook is visible here and it almost looks like a crossbill.

Yellow-throated Vireo

I was interested in this phenomenon, as there had been an article in Birding magazine several years ago about beak deformities in Black-capped Chickadees in Alaska. I did a Google search for beak deformities and the only reference was the chickadees. So I guess it is a rare occurrence. I was pleased to get a photo of it. I only noticed it after getting home and looking at the photos on the computer and I knew something was wrong with the beak., Fortunately, I had a number of photos and could ascertain the problem. Thanks to those who took the time to send in their answers.

Happy birding and photography,
