This is really the question. I use the term lek, because
the adjacent territories are literally only a few meters in
area with lots of territorial displays, whisking displays
over females and lots of chasing. I just don't know what
else to call it. Male mist-net captures are concentrated
an open area, which is where we see most of the displaying
chasing and whisking. Female captures split between the areas
where males concentrate and areas with plenty of cover
consistant with nesting habitat. This activity goes on
from late-March through mid-April, then abruptly stops.
Late-May and early-June we start catching hatch-years.

Rufous Hummingbirds have been reported to nest in colonies
of up to 20 with nests only a few meters apart. This, of
course, is not lekking but it is interesting, especially
since the behavior appears to have been reported at Cape
Disappointment.

Half-a-bee, philosophically must ipso-facto half not-be.
But half the bee, has got to bee Vis-a-vis its entity...
d'you see?
But can a bee be said to be or not to be an entire bee
When half the bee is not a bee due to some ancient injury?
