Cascadia Hummingbird Report - May 17, 2004

Rufous Hummingbirds have now been reported from just about as
far north and as far east as they go in their breeding range.

I caught the first juvenile of the season for the Neawanna
Banding Station Sunday, a hatch-year male. I had a likely hatch-
year female last week, but she managed to get away before I could
check for sure.

For comparison, here are the earliest HY captures for the past
four years at Neawanna Banding Station:

My best guess is that the unusually dry, warm spring has contributed
to the early appearance of young of the year. The monthly average
for April was 2.4°F above the norm and there was only 2.85 inches of
rain which is about half normal. May is shaping up to be warmer and
drier, too.

Some species of flowers are blooming early and it's been a remarkable
spring butterfly season, as well.
