Blue-headed Vireo

birds, wildlife

The Blue-headed Vireo (Vireo solitarius) is a through-migrant in Missouri. It winters throughout the southern Atlantic and gulf states, Mexico and parts of Central America. This vireo nests in cool temperate forests across Canada and in high elevations of the Appalachian Mountains. This is a species that will be threatened by the continued loss of the boreal forests of Canada. You can hear its sweet song in the spring in Missouri at places like Tower Grove Park where this photograph was taken.

The Blue-headed Vireo is an attractive Vireo that is seen in the spring and fall in the St. Louis area.
The song of the Blue-headed Vireo sounds much like a Red-eyed Vireo that is taking its time.

Clarksville MO, Lock & Dam #24 – Bald Eagle – 2021

birds, wildlife, wildlife photography

A juvenile bald eagle coming in for its prey.

We actually had a couple weeks of a deep freeze, old-fashioned winter during the 2020/2021 season. It was enough to get a lot of ice on our rivers and lakes but it didn’t seem to be quite long enough to bring the eagles into Lock and Dam #24 in big numbers. A couple friends and I tried during the last couple days of the deep freeze and although we had fewer than 12 birds, there were opportunities that made it worth our time. Here are a couple photos of a juvenile eagle (a 1.5 to 2.5 year old bird) that I captured as it came to the water to catch a fish that was stunned following its passage through the dam.

A catch!

Check back soon as I will be posting more photos of eagles and other birds that were making their living in the open waters beneath Lock and Damn #24.

Brewer’s Duck

birds, wildlife, wildlife photography

The Brewer’s Duck is a hybrid between a Mallard and a Gadwall

Although I cannot count it as a new species on my lists, I do believe this bird is worthy of a little attention. The “Brewer’s Duck” has been noticed for centuries, even being painted by J. J. Audubon himself. But, he called it the “Bemaculated Duck”, an apparent misspelling of the descriptor, bimaculated, meaning “marked with two spots.” The Brewer’s Duck is an intergeneric hybrid between a Mallard (Anas platyrhynchos) and a Gadwall (Mareca strepera).

This bird was originally spotted at Bush Conservation Area on February 23rd by Michelle Davis and reported via eBird and MOBIRDS. These photos were taken on February 24th.

The Brewer’s Duck is a true blending of its two-species heritage and they apparently are quite variable in appearance.

In the above photo, the blue speculum patch can be seen, coming from the Mallard. The fine lines of the Gadwall can be seen on the breast and sides. The head is a mixture of both species. Some green can be seen towards the back of the head, although this could only be seen at just the right angle to the sun. The bill is also a mix of the yellow Mallard’s and the all black Gadwall. In my opinion, the feet are more reminiscent of the color of the Gadwall’s feet.

A nice comparison of Mallard, Brewer’s and Gadwall drakes.

So far I have been unable to find out much about the Brewer’s Duck from books or internet sources and I have lots of questions. This bird seemed to mostly associate with Gadwalls. Is this common, or does it depend on which species was the mother? Does the parentage have to be directional? Are they fertile? How common are they?

Thanks for the visit!
