Cascadia Hummingbird Report - 03/28/2005

Weather this week has been stormy and wet with temperatures around
normal (a bit warmer in some placer and colder in others).  This
appears to have slowed the migration.

Lee Cain and his daughter sent in this observation, which definitely
falls into the unusual behavior category:
"Naomi and I experienced the coolest hummer behavior I have seen 
yet at Lagoon Lake in the Oregon sand dunes [Lane Co near Florence]. 
As we were walking around the campground trail, a female RUFOUS 
HUMMINGBIRD zoomed in to a spot about 2 meters from our feet, and lit 
on the GROUND at a recently dried up puddle. She then began scarfing 
down some tiny critters while actually standing on her two little 
feet -- she was not hovering.  We watched transfixed, and then as 
soon as she had buzzed away, we got down on our hands and knees to 
see what she had been after.  Coming out of the mud were 3 or 4 tiny 
emerging midge adults, and I am fairly certain that these must have 
been what she was eating."

Of course, insect eating is a well known behavior.  Insects are 
probably the primary nutritional food source for early arriving
Rufous Hummingbirds and an important protein source for nestlings. 
I've seen both Rufous and Anna's Hummingbirds work hatch-clouds 
of flying midges on many occasions, but ground pecking for emergent
bugs is a new one on me.
