According to some genetic research that was done on southern Appalachian
ravens, our ravens are genetically identical to other ravens in North
America (except for a population in sw US). More data is needed before a
final conclusion should be made though.
I have been out checking on raven nests. The following is information that
I have gathered in the last three weeks:
On 4-6-02, I re-located the raven nest in Shady Valley. This nest was found
last year by Troy Ettel and myself. There was no new material added to the
nest, in fact, much of the nest material was at the base of the cliff. At
one point, I witnessed a Red-tailed Hawk following a screaming raven. The
raven got above the hawk and began mobbing it. Later, the raven came back
and started "scolding" me. I left the nest site to get a better angle. I
saw at least one young in the nest. There were possibly two. Only one
adult raven was seen. This is an abberation to what I believe is normal. I
always see two adults at the nest especially when they are scolding an
intruder. I looked along the roads for a dead raven but found none.
Also on 4-6, I climbed to the fire tower on Doe Mountain WMA. A nest was
reported on the tower last year. There was no nest or any sign of a nest.
I must have misunderstood the location. Of note: three male sapsuckers were
displaying to each other at the fire tower. No females seen.
I visited the Watauga Limestone Quarry nest on 4-29 to find no ravens during
my half hour visit.
On 4-29, I visited Doe River Gorge to find no ravens during my one hour
visit.
On 4-29, I visited a nest in Carter County to find two adults and young in
the nest.
On 4-30, I visited a nest in Unicoi County to find the nest empty. This
nest was first found in 1999. The nest had young every year except for this
year since.
On 4-30, I visited the Rocky Fork nest to see one adult going to the nest
area. I re-visited this nest on 5-7. No raven was seen in the nest
vicinity, but I only watched for 12 minutes (this is not enough time for any
confirmation).
The Devil's Looking Glass Nest has ravens going to the nest.
A nest site in the Smokies has ravens at the nest.
Summary:
of the 8 known nests visited, 5 most likely have young. I need to visit a
few more sites.
