Despite the continued cooler than normal weather with quite a bit of clouds and occasional rain the birds continue to arrive over the last week.  Among the many highlights were three different male Cape May Warblers, a Brewster's and Lawrence's Warbler yesterday, the continued Blue winged x Golden winged Warbler hybrid and my first Bay breasted, Wilson's, Canada and Blackpoll Warblers.  As of today I have found a total of 28 species of warbler around here plus the various hybrids.  Finding the two named 'winged' hybrids on the same day is not something I have ever done before.
