It’s always a production when swallows return to the Pacific Northwest each spring.
Our first glimpses of their arrival is often while they’re “performing”: swooping and looping through the air like the happy, noisy, carefree daredevils they are, chasing their food on the wing. They bring to mind a medieval circus troupe putting on airs as they enter a village, already dancing to get the attention of the townsfolk.
The Violet-green was the first species of swallow to show up in our neighborhood this year, claiming prime nesting spots before their Barn Swallow cousins could arrive. As their aerial maneuvers cast spiraling shadows on our sunny lawn, I soon realized it was a group of six or seven that had arrived together, and they’ve been putting on their shows ever since.
And while we’re on the subject of performers, I must say that the Violet-green seems best suited to be one more than any other swallow – especially the male, who arrives in full costume and makeup. Maybe too much makeup. For some time now, his get-up has reminded me of a certain Batman nemesis…possibly this one:
Far from being a joker, this beautiful and cheerful bird is a true delight and nothing to summon Batman for. The most trouble Violet-greens are likely to get into is when they attempt to nest where they shouldn’t, like the one above, whom we recently found in our garage. He was quickly let out and all was well. (The bird, that is, not Jack Nicholson. He may still be in there somewhere.)
Read on to learn more about the lively Violet-green Swallow.
Scientific name: Tachycineta thalassina
Size and markings: The Violet-green Swallow is 4.5 – 5 inches long with a wingspan of 10.5 inches. Its iridescent upperparts are a greenish-bronze with touches of violet on the shoulders. The rump and upper tail are also tinged with violet and surrounded by white on each side. The male’s head is a full green, often a slightly different shade than the green on his back, which can appear more teal in color. The female’s head is lighter with bronze coloring on her crown. The bill is small and black. Wings are long and its tail is forked. Its underparts are white, as is the face, with the white reaching over the eye. At the front of the eye is a dark spot, most noticeable on the male.
Food: The diet of the Violet-green Swallow consists of flying insects, which it catches on the wing (while flying).
Habitat/nesting/behavior: Suburban areas and even cities will find this swallow returning year after year to the same nesting sites. It will choose nesting boxes, crevices in buildings, ledges in open carports, and available tree cavities. Its nest is woven together with twigs, rootlets, and grasses, and then lined with soft feathers.
Number of broods per year: 1-2
Number of eggs per year: 4-6
Migratory pattern: The Violet-green Swallow spends its summers in western North America, nesting from northern Mexico all the way to Alaska. It also lives year-round in much of Mexico, where the swallows who’ve migrated will return for winter. Watch for this bird to return to the Pacific Northwest starting in late April (or earlier) into May, when you’ll see it sitting on power lines or swooping acrobatically above its chosen territory as it chases food and chirps excitedly.
Months usually seen at backyard feeders: The Violet-green Swallow is not a feeder bird, but you can still be thrilled by the acrobatics of this suburban nester during the late spring and summer months.
