Birds of the Week # 45

American Robin

The American Robin (Turdus migratorius) is a migratory songbird of the true thrush genus and Turdidae, the wider thrush family. According to the Partners in Flight database (2019), the American robin is the most abundant bird in North America (with 370,000,000 individuals), ahead of red-winged blackbirds, introduced European starlings, mourning doves and house finches. It has seven subspecies, but only one of them, the San Lucas robin (T. m. confinis) of Baja California Sur, is particularly distinctive, with pale gray-brown underparts. The adult robin’s main predator is the domestic cat, other predators include hawks and snakes. When feeding in flocks, it can be vigilant, watching other birds for reactions to predators. Brown-headed cowbirds (Molothrus ater) lay their eggs in robin nests (see brood parasite), but the robins usually reject the egg.

Yellow – rumped Warbler

The Yellow-rumped Warbler (Setophaga coronata) is a regular North American bird species that can be commonly observed all across the continent. During the breeding season, the yellow-rumped warbler is generally known to be residing in either exclusively coniferous areas across the North American continent, or mixed coniferous-deciduous habitats where coniferous forests merge with trees like aspen (Populus spp.) and willow (Salix spp.), etc. Many of its habitats in the western U.S. tend to be mountainous, but it can also inhabit places at the sea level as long as there are conifers presentβ€”which is the case of its habitats in the Pacific Northwest and the Northeast of the United States.

  1. Two of my favorite American birds, HJ, and lovely to see them featured here. I didn’t know robins were our most abundant bird in N.A. Truly a joy to have on this planet. And the yellow-rumped warblers are also a joy. We have them in the winter too in Calif. and I love seeing and hearing them in parking lots and urban centers. Nice photo highlighting the yellow rump. Delightful post, my friend.

  2. It’s always a pleasure to have your visit, Jet. Just this morning when I went to refill the feeders, I saw 5 A.Robins hanging out in the lawn next to the deck. The :”butternuts” are always welcome to my backyard. Thank you, my friend. πŸ™‚
