2 It is staggering to think that of the 10,000 species of birds in existence today, many have been around for much much longer than we have walked the earth. On a related note: after more than 40 years of being lumped together as Yellow-Rumped Warblers, three variants–Myrtle, Audubon, and Goldman’s–may soon be split back into their separate species, thanks to recent discoveries that suggest that their DNAs have diverged significantly over the last million years 1 to the point that they are indeed different warbler species. The variant of Yellow-Rumped Warblers that tends to be seen most often in Metro Vancouver and Western Canada is the Audubon variety, which has, as one of its more recognizable field marks, an additional yellow patch on its throat (interestingly, though, it was the Myrtle variant who figured into my latest photos). They also stick around much longer than other neotropical migrants will, so chances are good that if you hearing lots of singing and see plenty of wings fluttering in a tree, you’re witnessing a flock of Yellow-Rumped Warblers feeding and foraging.Īn adult male YRWA in fall attire at Boundary Bay Wildlife Area on October 5, 2016 Once in a while, though, a few of these extremely sociable warblers (usually juveniles or females) may decide to be a little more co-operative and pause long enough for me to photograph them. “Butterbutts”, as they are sometimes affectionately known to birders, are among the best known of songbirds in the Northern Hemisphere. But by the time I had my camera raised, said dad–who was a tantalizing 6-7 feet away from me–had flown off to a far less accessible perch in one of the 100-foot Douglas Firs in the backyard.Ī juvenile/female YRWA poses for a photo at the Boundary Bay Wildlife Area on September 15, 2016 I did get a glimpse of a handsome male this summer–and he had the unfortunate distinction of being adoptive father to (at least) one juvenile Brown-Headed Cowbird. I have yet to photograph these beautiful songbirds at close range in their breeding plumage, as these insect-and-fruit eaters tend to be high up in the trees in the spring and summer, and they are rarely still for moment than a few seconds. Active balls of energy who constantly hop and/or fly from bush to tree, YRWAs may show off their visually most dazzling wardrobes in the spring, with dashing hues of black, white, grey and bright yellow, but autumn is when they gather in huge droves to feast on fall berries, just as insects are starting to become scarce.ĭistant shot of an adult male YRWA (Myrtle variant) at Colony Farm on April 18, 2015 This gallery contains 3 photos. It hardly seems fair–or flattering–to be described by the colour of your bottom, especially when you are those pretty songbirds known as Yellow-Rumped Warblers.
