Although many warblers are arriving in places throughout the Southern and Central states over two weeks earlier than normal, so far we haven't had an enormous surge of oriole migration.
Orioles are tropical migrants, and their migration is closely timed with daylength.
Even so, every now and then we get a weird bird that jumps the gun. Such as the report of a Baltimore oriole seen during the first week of April in Minneapolis. Strong southeast winds blew birds inland, so birders had to work hard to find any land birds in the woods. See this week's weather report from Dr. David Aborn One of the interesting birds to turn up in Texas, in Rangerville, on April 10, was a Fork-tailed Flycatcher. These beautiful birds truly belong in the tropics, in Central and South America.
