1978 Walter D. Koenig Malamerpes formicivorus Read I Hastings Reservation (19 February) Counted stores: Main tree: 1211 (have they moved a lot into here? possibly recovered from the sycamore?) Remains of sycamore: 31 Others: 62 Total 1304 21 February 1415. Watching the fallen sycamore to see if I can catch (see) some birds salvaging acorns. 1515.
