[Tweeters] Swifts late

[Larry Schwitters via Tweeters]

Count Vaux’s Swifts as also being late in their northbound migration this year. All of our roosts north of Oregon have been having a lot less than their expected numbers.
But last night the San Diego YWCA reported 7600, their second highest number ever. The wee birds are usually gone from there come May.

So if migration is 2 weeks late, why?
