Not to start up the whole West Nile debate again, but I thought BCN would be
interested in some new data. I completed my Fish And Wildlife Service
Breeding Bird Survey Route that runs through DuPage County from near Wayne down to
Bolingbrook. This is a standardized census that has been run for over forty
years - starting in 1966.
I thought that Crow numbers seemed low, so I checked the previous years'
data which indicated that over the last five years the average numbers of crows
seen along the route was 70. In 2002, I had 85 crows.
This year, I only counted 12 crows, - a record low for over 40 years of data
collection.
Blue Jays were only slightly lower than average - I counted 9 and the average
is about 14, and Chickadees were right on the average at 11.
Other species such as Robins, Red-winged Blackbirds, Song Sparrows, House
Wrens were somewhat higher this year.
There are three other BBS routes in the Chicago area and it would be
interesting to see if those observers noted similar results.
