Brown-headed Cowbird Nestling
This spring and summer seem to have been very successful for the Brown-headed Cowbird. I realize that this is largely anecdotal, but I have had and heard a lot of sightings and stories about various species discovered feeding a hatchling or fledgling Cowbird. From the American Redstart to the Chipping Sparrow, the Yellow-throated Vireo or the Yellow Warbler, an Orchard Oriole and a Common Yellowthroat, a Blue-winged Warbler or this nest that I found and photographed a couple of weeks ago, it has been Cowbirds here, there, and everywhere. What’s the common thread? All of these birds and...

We seem to be at the peak season of reports of, “Why is this pretty bird feeding this huge baby bird that is twice its size?!” all thanks to the native Brown-headed Cowbird (Molothrus ater). Here we have a photo of a male followed by a female. The species is a brood parasite with the female laying eggs in nests of other birds to leave the burden of raising young to these unsuspecting parents by fooling them into thinking it is their own egg. It is also a rather clever way of not putting all of your eggs in one basket. These blackbirds are found in typical types of blackbird...
Read MoreCommon Yellowthroat
This male Common Yellowthroat (Geothlypis trichas) and I are rather close…or at least we were for about 30 seconds on a recent May morning. This bird is a migrant, though you may end up with a resident in a yard near you. Their common name does betray their abundance, and gardens, marshes, fields, forests or anywhere they can skulk about in dense, low vegetation works for them. Being a habitat generalist has helped the species end up as one of our most common warblers. It also makes them a frequent target of Brown-headed Cowbirds and brood parasitism, like the abundant Yellow Warbler....
Read MoreCooper’s Hawk
I have been posting many photos of migrant songbirds lately, and here is one of their predators – the Cooper’s Hawk (Accipiter cooperii). This raptor of the forest is an extremely agile and talented flier, able to navigate through thick woodlands in pursuit of prey. You may recognize them from your yard as they are frequent bird feeder guests, targeting hungry passerines. They seem to be less adept at capturing prey in open areas like this one, unable to fully utilize their maneuverability and relative speed as they do in more dense habitat to surprise and outwit songbirds. This...

This male Brown-headed Cowbird (Molothrus ater) was taking a look at all the maple seeds in this driveway, perhaps wondering why it shouldn’t eat all of this abundant and easy to grab food instead of those fast, pesky and tough to spot insects. They do primarily eat seeds, and I guess you have time to wonder these things when you leave the difficult task of raising your young to another species.
