[SBB] Junco and cowbird

["Hannes Vogel" <[[email protected]]>]

About two weeks ago, I saw the identical scene between an immature Cowbird
begging from an obliging Dark-Eyed Junco here at the Stanford Medical
Center. It was a little amusing seeing a bird feeding one about twice its
overall size. Also, I was so taken by the scene that as I stood and watched,
the Cowbird then shifted it's attention to me and hopped up to me for a
handout.

Yesterday outside my office window at Kifer and Lawrence in Sunnyvale, I had
a Dark-Eyed Junco feeding a young Brown-Headed Cowbird.  I've seen the
pictures of a small parent feeding a much larger chick but this was the
first time I've seen it live.  The cowbird was on a tree branch doing the
wing-fluttering begging behavior and the junco flew in with food.
 
This comes about a week after I heard a very exciting cowbird talk by
Stephen Rothstein at the Mono Basin Chautauqua.  For all its negative
impacts, the Brown-Headed Cowbird is a remarkable species.  For example,
unlike all other songbirds, the cowbird song (the gurgling intro followed by
high pitched whistle) turns out to be not learned but is innate, i.e. young
cowbirds isolated from other cowbirds will develop a normal song.  The
cowbird also has a flight whistle that is learned and has dialects over
geographical areas like many other songbirds.

Band-tailed Pigeons have been eating millet on my patio for the last 
week.  When I first saw them on Saturday, I thought it was a one time 
thing, but this is becoming a habit.  The loud flapping noise from 
the wings is distinctive.

This is an usual species for lowland Los Altos.

All,
 
At the Environmental Education Center this morning Frank Vanslager and I
had 
16-18 WILSON'S PHALAROPES (mostly in New Chicago Marsh), one RED-NECKED  
PHALAROPE (second island in Salt Pond A16), two BLACK SKIMMERS (third island
in  
the Salt Pond), up to eight LEAST SANDPIPERS and one breeding plumage
WESTERN  
SANDPIPER (sandpipers mostly on the second island).  A PEREGRINE FALCON was

on a power tower in Salt Pond A18.  Earlier we had checked out the  Coyote 
Creek Riparian Station ponds in hopes of finding a Little Blue Heron  but
alas, no 
joy.  Sigh!  
 
Take care,
Bob Reiling
