Spring tipu madness, Wilson’s Warbler glut

Spring tipu madness, Wilson’s Warbler glut

By – 10:27 am
A reasonable flight of passarines this morning at several coastal sites although not as many as yesterday at Mount Soledad, but same composition, with most common species at the latter site being 80 Wilson’s warblers and 40 warbling vireos, then smaller numbers of Townsend’s and Yellows and miscellaneous. Also the continuing Golden-crowned Sparrow. This spring throughout the county certainly has seen very impressive numbers of Wilson’s warblers, perhaps even record high numbers, and also well above average numbers of Warbling Vireos.Normally tipu trees are best and birdiest between about October and January, but in the last couple weeks or more it has become apparent that they have lots of food and lots of birds this spring, which is unusual. Not only here in San Diego County, but elsewhere in Southern California as well, including currently up in Santa Barbara. Dan King had a phenomenal number of birds this morning in a tipu parking lot in Sorrento Valley. And a couple of us checked a couple lots in UTC and in each lot had something like 20 Wilson’s and several each Warbling Vireos and Yellows and Townsends. So, think good tipu parking lots such as in Encinitas and Carlsbad and Del Mar and La Jolla that produced some of our rarities this past fall and winter, and certainly worth keeping an eye on them for another month through vagrant season till mid June.Paul Lehman, San DiegoSent from the all new AOL app for Android
