This seems like an interesting and perhaps productive topic for a
thread. A few years ago now, while birding in southeast Colorado (USA)
in the winter, I came across the most spectacular flock of Red-winged
blackbirds. It rose in the distance, flying towards me, with birds from
the passage wetlands (mostly dry, but full of dry typha). When the
flock finally passed overhead, it was like a dark storm cloud on a late
afternoon. The light really was reduced, and the sound! A sort of
roaring whistled clatter. The flock took nearly 20 minutes to pass over
and I guestimated the birds to be in the millions. Thats the largest
number of anything (other than ants in my kitchen) that I've ever seen.
Also spectacular was the snowbank on the edge of the slough on the
Alberta prairie one late autumn. Yes, from a distance it looked like
snow. Strange, thought I. Snow is certainly believable at this time of
the year, but why is it just in one spot (even if it is a big spot)? As
I got closer, the snowbank errupted into wheeling flight... Snow Geese!
