I need to correct my previous posting. I should have said intergrade
instead of hybrid juncos They cannot be hybrids because the parental
types are only subspecies, not different species. As with flickers, the
term intergrade is the appropriate term.

Hi all,
The Nothrthern Pygmy-Owls are courting like crasy, last evening I took Nathan
Pieplow out to get some sound recordings of a pair of owls. They didn't let us
down. The little owls began calling about 7:20pm and didn't stop until a Great
Horned Owl flew over the calling male pygmy just
I had my FOS sighting of a Lincoln's Sparrow last Wed, 3/16, in my back yard.
It's continued to be present daily since. This is about 2 weeks+ earlier than
my previous years' FOS LISP sightings.

Thank you all for your comments.
1) Intergrade vs. Hybrid- The rigid definition is as Bruce describes, with
hybrid being ascribed to the interbreeding of two species, and intergrade
as a mixing of two subspecies. But this definition has its flaws, especially

Hi COBirders,
Still quiet here. Watched from 9:00-11:30, until I got blown off the ridge.
Best sighting was of three Red-tailed Hawks, 2 adults and 1 juv circling,
rising, and screaming only a couple of hundred feet away. Also saw one, twice,
(or two?) of the Garden of the Gods Prairie
Fascinating discussion, but almost impossible to follow because of the
addition of all the previous messages to the new message -- I have to parse the
thing over and over to find out what's new. As Todd, the listmaster, [and
thanks Todd, for your efforts] and his predecessors have urged, can
Hi all,
I'm prompted to respond to the thought-provoking comments of Bruce Webb
Christian Nunes, regarding the use of the word hybrid.
The definition of hybrid I have found is: The offspring of two animals
or plants of different races, breeds, varieties, species or genera. It goes

Our woodworking birder friend, driving in to our house this morning, clearly
saw a common/Wilson's snipe in the duck yard of our neighborhood, looking
perplexed. I guess it was thinking that ducks and water usually go together,
and yet here was a band of know-nothings hanging around a barren
Greetings All,
Sorry, I have been trying to set up household and learn an array of new
systems. My first two attempts to post to COBIRDS failed, due to my own
misapprehensions (in other words, I have been a dunderhead).
On 19 March, Nick Komar and I visited a number of sites in Larimer and
This morning, about an hour after sunrise I saw a Bufflehead dabbling
around the edge of Tom Frost Reservoir in Broomfield (NW corner of
Lowell and Midway).

Junco. I get pink-sided most days.
On I had two Bushtit and continuing Mountain Chickadees. I have not had

Hi all,
Just had a Bobcat walk through the back yard. It stopped briefly, caught a vole
and walked off. This cat has been in the neighborhood since October last year.
Thought some of you might find that interesting.

Yesterday (21 March, first day of calendar Spring) I found a pair of Osprey
setting up housekeeping on a nest platform in the SWA on the south side of
Pueblo Reservoir. I also had a brief distant look at an American White Pelican,
later seen by another birder. Both are my FOS. The Osprey were
Today (March 22), at about 10 am Rudy Badia and I saw a second year Harris's
Sparrow at the RMBO office at Barr Lake State Park (Adams Co.). It was
hanging out with several White-crowned Sparrows. Too much wind to enjoy
scanning the lake. We also saw a flock of about 40 American White Pelicans
On Lower Church Ranch Lake this later afternoon, right around sunset, in the
howling gales, there were 2 Yellowlegs, looked like Lesser but I couldn;t hear
them because of the wind. (I was also too chicken to get out and set up a
scope because of the cold, wind, and blowing debris). There
