NATURE CLICKS #507 - BLUE-GRAY GNATCATCHER (AND MORE)


Blue-gray Gnatcatcher

The Metadata of my picture library reveal that we have never seen a Blue-gray Gnatcatcher at the height of the summer here in our woods. Occasionally I had one in late spring or very early summer in front of the lens. They move very fast up and down on the outer branches and shrubs in search for all kinds of small insects and spiders. This makes taking a sharp image that shows the whole bird a big challenge. You can’t really shoot from a tripod because it would make following the bird’s moves impossible. Changing position constantly and handholding the camera with the long lens is the best option as far as I’m concerned.

This bird is either a female or a juvenile that was born earlier this breeding season. Blue-gray Gnatcatchers can built up to seven nests during one season and have 1-2 broods. There are many reasons for nest loss or brood failure, from parasitism or mite infestation to predation.

By the way, our young House Wrens, I had posted about yesterday, Ieft the gourd with the nest this morning at sunrise. I saw the last one jumping into some house plants that we keep on the porch during the summer. Later I heard their chatter in the nearby woods. I hope they all will make it! The male House Wren is already on courtship again and tries to attract a female to one of the other nest boxes. All seasons during a year have exciting moments. The wrens leaving the nest is always one of them!

NATURE CLICKS #491 - BROWN-HEADED COWBIRD


Male Brown-headed Cowbird

The neotropical migrating birds are not even here yet but the cowbirds are already in position. The Brown-headed Cowbird is North America’s best known brood parasite. They do not built their own nests but instead lay the eggs in the nest of many other bird species. This is not always in favor of the host birds, because cowbirds hatch and develop faster and sometimes toss out other nestlings or eggs. This male cowbird posed nicely in the early morning sun today.

The female Brown-headed Cowbird doesn’t come to mind quickly if we think about an attractive bird. It needs something different to tell a story about this bird. I used the texture of the fresh leaves in a bush of peonies to make the gray of the cowbird’s feathers stand out. The bird had just landed on the metal ring that holds the flowers together and started spreading its tail and feathers. That little gesture makes all the difference between this shot and several other ones I took with the bird hopping on the ground.

We see the Brown-headed Cowbird only occasionally. They are nest parasites and go around and lay one egg in the nest of another bird species. I read that up to thirty-six eggs are laid per nesting season. They hatch usually first and outcompete the young birds of the host. (source: iBird Pro app)
