hummingbird update
One of the two eggs hatched several days ago, but I can’t tell if the baby is actually alive. I haven’t heard it cheep, and whenever I peek it appears to be sleeping in this same position. The mama is either away from the nest, or sitting on it; I haven’t observed her bringing food to the hatchling. I’m keeping my fingers crossed for a successful outcome here, but I’m not feeling very optimistic.
learning birdsong
I only had a few minutes to sketch before work, and in the time it took me to draw a Foothill Penstemon, the Merlin app identified 19 nearby bird songs. I can recognise seven (maybe eight) of those birds by ear; I plan to keep studying their calls, and one day know them all.
Oxyura jamaicensis
A new-to-me waterbird at Legacy Park! I was delighted by the bright blue bill on this male ruddy duck.
I’ve read that ruddy ducks are very aggressive toward each other and toward other species, but this fellow was behaving peacefully. Apparently they will even chase rabbits feeding on the shore. During courtship, males beat their bill against their neck hard enough to create a swirl of bubbles in the water. Pretty intense!
The genus name Oxyura is derived from Ancient Greek oxus meaning “sharp”, and oura meaning “tail”. Ruddy ducks were imported into the UK in 1948 and have since spread to Europe, where they are considered invasive.
Selasphorus sasin
We’re delighted to see a hummingbird nesting close by the house, though it means we have to creep past so as not to disturb her. Two years ago, when the lemonadeberry was bigger and closer to the pathway (and thus more easily disturbed), a hummer hatched two babies there, but they died before fledging. We never knew if our presence disturbed the mama too much, or there was some other reason for the fatalities. Fingers crossed for a successful raising this year.
The Allen’s hummingbird constructs her nest out of plant fibers and down, coating it with lichens and spider webs to give it structure. There’s likely one or two eggs, which she will incubate for 15 to 17 days. The young leave the nest about three weeks after hatching, so we might have another month of fun (cautious) viewing.
Icterus cucullatus
Happy to see Mr Hooded Oriole back in the ’hood. Is he raising a family nearby? Or was that all done elsewhere, before he arrived?
Biodiversity
In honour of International Day for Biological Diversity, here are the birds I’ve seen at home over the past couple of days. I made an attempt at relative sizing, but I think the oriole ended up a bit small.
Toxostoma redivivum
Fun morning sighting. I only ever see one thrasher at a time, usually dashing across the driveway, so I don’t know if there are multiples here. But I’m always happy to spot this mockingbird relative.
Pandion haliaetus
I’ve been seeing the osprey hanging about this month, but my eyes and camera aren’t up to the task of recording the finer details. Big thanks to local birder-photographer Chris Tosdevin for this great original image; I had fun sketching it.
Quiscalus mexicanus
Great-tailed grackles do indeed have great tails—they can fold them in half to make a vertical presentation. These birds are larger than starlings but smaller than crows. Males are iridescent black which sometimes has them simply called “blackbirds”. Females are brown with darker wings and tail.
It’s breeding season, and there’s a lot of grackle activity (and song!) going on at Legacy Park, where they are sharing space with red-winged blackbirds, another beautiful and melodious black bird.
