Asynchronous Lewis
San Antonio Valley, Santa Clara Co., California
(28 May) babies that he wanted for some switches.
All the Lewis' were ~10-20 day old category - quite synchronous, as well as fairly close together and,
because the holes were relatively large, fairly easy
to open. All in all, it seemed like they'd be pretty easy
to study out here, as nests are not hard to find and adults
would not be hard to band. It's good to know that the
population here is doing fine 20 yrs after Carl Bock
watched them (actually closer to 25 yrs).
We drove back (with 12 screaming babies in the car)
by going up [illegible] and out Del Puerto Canyon Rd to Hwy 5.
This all made for a long day - we got back to Hastings about
1530 or 1600, and we're very lucky to have managed that
(we did only because we found nests so fast). Incredibly
evenough, the transplant experiment is going to take place!
We also noted as a final point that the small brood sizes
(1-3, Mean of 2 [n=4]) we found contrasts with the
rather large clutch size of Lewis' Woodpeckers, which is
slightly larger than Acorn Woodpeckers. So, there must
be lots of brood reduction in this species!
Hastings Reservation, Monterey Co., California
We started by adding the 3 youngish babies (2 from 1
brood and the nunt from The brood of 3) to CV Grande,
where they otherwise have only 2 babies. We then
went and banded Road 1, adding two of the remaining
chickes (the younger of those left) to their 4. This
