Brown-headed Cowbird juvenile


"The Brown-headed Cowbird is a stocky blackbird with a fascinating approach to raising its young. Females forgo building nests and instead put all their energy into producing eggs, sometimes more than three dozen a summer. These they lay in the nests of other birds, abandoning their young to foster parents, usually at the expense of at least some of the host’s own chicks. Once confined to the open grasslands of middle North America, cowbirds have surged in numbers and range as humans built towns and cleared woods.
Brown-headed Cowbird lay eggs in the nests of more than 220 species of birds. Recent genetic analyses have shown that most individual females specialize on one particular host species.
Some birds, such as the Yellow Warbler, can recognize cowbird eggs but are too small to get the eggs out of their nests. Instead, they build a new nest over the top of the old one and hope cowbirds don’t come back. Some larger species puncture or grab cowbird eggs and throw them out of the nest. But the majority of hosts don’t recognize cowbird eggs at all." From AllAboutBirds.

This evening, I have posted a dozen photos taken yesterday evening, 30 July 2019, on a birding walk in Fish Creek Park. The Black-crowned Night-Heron was the highlight for us. A few other species were seen, but many were distant and either I didn't bother to try and get photos, or else I have posted them just for the record.
I rarely go on an evening walk, but yesterday evening was beautiful weather for walking, and, as always, it was nice to spend time with friends. Thanks, Anne B., for giving up your evening for us!
Today, we are under a Severe Thunderstorm Watch. We have a hot day tomorrow, 29C (to feel like 31C). With my place feeling like an oven, I might just have to make use of my car's air-conditioning. A drive also might help take my mind off a very painful toothache, caused by two teeth I had filled about a month ago. I hadn't had toothache for many, many years - now I remember what it's like. I have a dentist appointment on Friday.
