I've finally had the chance to update the trend analysis
for the Rufous Hummingbird migration front to include the
two most recent reports from Alaska. The straight line
trend first noted along the Oregon Coast holds up for
coastal detections all the way to Juneau.
Just about 30km/day.

Isn't nature wonderful?
