A Yellow-rumped Warbler is spotted Saturday outside a residence in Pajarito Acres. These birds typically forage in the outer tree canopies at middle heights. They’re active, and you’ll often see them sally out to catch insects in midair, sometimes on long flights. In winter they spend lots of time eating berries from shrubs, and they often travel in large flocks. Source: allaboutbirds.org. Photo by Richard Henderson
