1988 M. Stanback M. Formicivorus (18 Mar) Some oak comparisons. The curve oak (with the huge acorns) has thick leaves that are yellow on the under- side (like a golden oak) The leaves (esp the newer ones) are rather fuzzy, dusty as well. I Found another oak with smaller, shinier leaves (green underneath) that appears to have dropped acorns not too long ago. The caps are much smaller than those on the curve oaks. The bark of this tree has a orange tint to it (probably lichen) The newest leaves seem greener than the new leaves on the other oak (with their [illegible] red color) 1512 ACW landed at acorn and started pecking. I couldn't tell whether it had already been opened (I think it had, For the bird was quite soon eating from a rather large opening) It ate until 1515, when another bird (a ♀) displaced it and began eating. This bird left at 1517. Feeding birds are forced to eat in rather precarious positions, [illegible] similar to those of Hastings birds removing acorns. Again, I can't say that all the birds at the curve tree are from 1 group, but there are at least 4 birds that sit peacefully together in the little snag to the W of it between forays into the big tree. Like the Hastings birds, there is some color variation in these guys. The other day I noticed a bird w red (or a fleck of gold) on its chin. In general, these birds are slightly duskier on the belly than Hastings birds, but not much. Just heard an alarm call for a low flying red-tail. (The other day I noticed about 12 RTHA flying together.) I haven't seen any
