Melanerpes fornicivus
Lambert Hastings Reservation
25 April 920. A bird hawking from the "middle" tree, the big old VD
along the road up between Keep Out and Lambert.
28 April 1155. 2, possibly 3 (1 getting chased) birds here. Some Garricks .
1200. Now 4 birds; chases. At least 1 unbanded bird; also
a banded bird. ①♀ or /M#283; ②♂ub.
1203. ♂ drumming. 5 banded (♂ or /Bile or?) getting chased.
1210. Now no longer clear who's chased and chaser between
the ♂♂. ♂ is #284! These are the 2 siblings back from
last fall!
1215. ♂ub I think is doing more chasing than vice-versa.
1220. Seems like either ♂ is scared of the other;
neither is quite sure of itself.
1223. Now ub ♂ chasing ♂284 back and forth. ♂283 pretty
passive through all this. A few more Garricks; some,
at least, being given by ♂284. Also, now he's doing some
chasing.
1230. Well- quite interesting. Two returnees, and several
questions- will the 2 sibs inbreed? (I think not- it's close but
♂ub seems to have the upper hand) Will ♂284 stay
anyway, even if ♂ub takes over? Quite exciting.
1231. All 3 next to each other (9 in between ♂♂) eating
catkins, but the ♂♂ are not at all happy with each other!
1235. ♂ub definitely ahead- ♂284 doing most of the Garricking
and getting chased; ♂ub with ♀ more often. These are
clearly the only main participants here.
29 April 1900. Nobody roosting here, as best as I could tell, on this
cool, fogged-in evening. No sign seen from any of the standard rules.
