[obol] Band-tailed Pigeons

[pamela johnston]

In late August we invited a pair of USGS researchers to come to our yard to 
trap and equip Band-tailed Pigeons with transmitters. They caught one in our 
yard and 3 at our neighbor's feeders. It has been interesting to monitor 
them online, because they haven't all done the same thing. Two are in 
California and one hasn't been farther away than Newberg.

choosing an number you can see where they've gone.

  Although I haven't seen a flock of 35 like Greg, I have noticed more of 
this species this October than the previous three Octobers.

  Around mid-September, I noticed that the two pairs that bred near my house 
(and their offspring) were gone, and my sightings of this species in SW 
Portland decreased.  Then, over the past two weeks, I've noticed an increase 
over what I was seeing in mid September.  Although I'm not keeping track of 
the counts, I believe I'm seeing at least 6+ per day while going about my 
non-birding activities in SW Portland.  This stands out to me as being 
unusual relative to the previous three Octobers I've lived here.  Anyone 
happen to know their peak migration date?  Average departure date? 
Percentage of breeding population that does not migrate?

    Columba fasciata monilis: 35 in a flock over Hagg Lake was a bit late, I
    thought, for the forest birds. A few sometimes winter in residential 
areas
    with feeders.
