Melanerpes formicivorus
Westgate Hastings Reservation
27 May 1530-1800. Searched and watched for a nest here. If this
group does have a nest, which I consider likely but by no means
certain at this point, they are managing to elude my most
experienced and discriminating attempts to find it in a way
matched by few other groups in recent years.
31 May 1600. At long last - a bird was looking out of the hole in the Valley Oak
back by the Corral. Their nest, no doubt.
1 June 1400. Checked and opened the hole (nobody was in it) where there are
3 fresh eggs! (Eggs were marked)
3 June 1400. Flushing a bird from the hole, there are ### 5 eggs here.
5 June 1500. Still the same 5 eggs here, warm.
Counted stores: 873
14 June 1000. Came over to begin setting up nets. Flushing the ♀ out of the
hole, it was clear the babies had hatched.
1430. Before putting up a net I checked the hole: 4 newly
hatched babies plus 1 egg (#4), which is opaque and will
probably hatch yet.
15 June 1630. After waiting ½ hr or so I got the ♀ in the hole by
trapping her with my long pole put in front of the
entrance. I quickly banded her as #599. In the process
I also checked the nest, where all 5 eggs have hatched
and all 5 babies are present.
17 June 1600. Weighed the babies, of whom 4 are still around. Also moved the
bar I put up the evening of the 15th to help #858 make it into the
hole with his stump leg.
22 June Given watched here this evening and reported #858 unable to
make it into the hole to roost, despite numerous attempts. So I
