Melanerpes formicivorus
Road 1
Hastings Reservation
(2 May) I returned about 1100 and even though nobody uses in the
holes I checked the 2 likely ones anyway. Nothing, however.
4 May Drove by about 800 flushing a bird from the lower hole
facing the road in the sapmore. Could be it, I suppose.
7 May 1920. Flushed a bird from one of the upper holes facing the road -
I sure hope that's not it! I've seen nobody in that other
hole since the May 4 entry.
8 May 1150. Bird flushed from lower hole facing the road again.
1330. Hole opened: 6 eggs!
9 May 1250. I'm in luck. Eggs! Yahoo!
10 May 1530. Egg check yielded no more eggs.
20 May 1130. Counted stores: main tree: 1265
Nest tree: 407
Others 23
}
22 May 1815. Measured babies, 6 of whom made it. They are 3-4 days old,
so I suspect that one egg just didn't hatch rather than
the alternatives (starvation, [illegible] accidental injury).
30 May 1105. ♂222 flushed from the road (he was on the road) while driving
6q.
1 June 1855. A bird was flushed from the nest tree, possibly from the
late '75 nest hole - a 2nd nest possibly?
6 June 910. ♂181 flushed from on road right near the nest tree.
1030. ♂183 seen at nest hole.
1740. Watching from hide (at nest tree). Flushed 2 birds from late '75 nest
hole - were these birds roosting already or do they have a second nest?
Nobody in storage tree, but some calling coming from forest above the
storage area field.
