Marty et al,
Two insects known to live under eaves are: European Paper Wasp (Polistes dominulus and native paper wasp relatives in the genus Polistes make paper combs containing 10-20 cells each) and I have seen a lot of praying mantis egg cases under eaves and on the upper part of brick walls shaded by the eaves. The Black-and-Yellow Mud Dauber (Sceliphron caementarium) often sticks its mud cells provisioned with spiders in such microsites. Probably other possibilities like spiders, spider egg sacs, dead insects trapped in spider webbing, harvestmen (aka daddy-longlegs), swallowtail butterfly chrysalises, etc. One thing they are NOT after are boxelder bugs, which often congregate on house walls (and come inside if they can gain entry). As far as I can tell, NO bird will touch them, apparently due to toxic or otherwise nasty sequestered compounds. Regarding the most likely insects, at CBC times of the year, woodpeckers and other birds could be going after unhatched larvae, cadavers, or, in the case of the mud dauber, provisioned live but stunned prey contained in the mud cells. And you might very well be right about dripping water.

Several years ago when my CO Spgs Area 11 CBC crew first spotted the female Acorn Woodpecker along Cheyenne Blvd in mid-Dec., it and a N. Flicker were both clinging to and working along the fascia on front of the roof overhang of a house, picking at or lapping up some unknown grubs or eggs (or dripping water from snow on the roof shingles??), from under the slight shingle extension beyond the fascia boards. As subsequent sightings mostly occurred on or en route to/from a neighboring house's suet cages, I figured the roof-edge attraction must have been dripping water, but I've always wondered... Has anyone ever looked closely at that type of surface; are there sometimes sufficient numbers of eggs or hatched grubs there that could make it a repeatable food attraction for woodpeckers?

This is not a report of unusual birds, but I've had three recent observations of interesting Norther Flicker behavior that I thought would be fun to share.
-- In my yard a few days ago a flicker was attracted to suet hanging in a cage from the end of a branch. Apparently deciding he didn't want to, or couldn't, land on the cage itself, he perched directly over it, more than a body length away. He hung down and pointed his body and neck straight down and extended his tongue to the suet. The tongue darted in and out to a length that appeared to be over two lengths of the bill as he licked the suet. I'm not sure how much he got from the licking, but he stuck at it for several minutes. Other times flickers simply land on the cage and get bill fulls of suet; I'm not sure why this one did other wise. But it was fun to see that long pink tongue darting out so far!
About a week ago two flickers spent most of two hours foraging under the eaves of two moderately large buildings on the grounds of St.Mary Catholic Church in Littleton. They were after some morsels where vertical outside walls met roof overhangs. I've seen flickers work such niches before, but never in such a dedicated fashion over such a long period.
Lastly, yesterday a young female Cooper's Hawk perched in a tree near my home and was mobbed by three flickers that came to gather round its perch, taking a variety of aggressive postures, with much bobbing and bill pointing, some wing flashes, and a bunch of raucous calls. They never came less than 2 feet from the hawk, which seemed annoyed but unmoved.
