A Brewers is a great find and wonderful surprise!  I have looked and looked for 
one among our many feeder "hoodlums", but have yet to see one here.  We 
have had a drop in the number of blackbirds/cowbirds/grackles at the feeders 
this week (down to less than 100 had a time!), but I hope the mention of this 
does not jinx me!

Yesterday morning at 6:25 out back, there were two WINTER WRENS having a 
singing duel - it was great!  They are often around here in winter but I don't 
see them routinely, and they're secretive so I hear them even less.  Usually if 
I do it is in the evening, right before dusk, and not nearly as enthusiastic (long 
or loud) as what I heard yesterday.  The two birds were about 150-200 feet 
apart and belting out each song with gusto.  The duel lasted about 5 minutes 
and then they took a sudden break, but I had to go and don't know if they 
resumed.  For such a small bird they can really wail!

Cheers-
