It appears our yard Baltimore Oriole has returned.  We had one in the 
neighborhood last year, but were too busy atlasing to pay it proper 
attention.  While doing yard work last January, Dan noticed an Oriole 
nest in the sycamore tree behind our yard, so it looks like it must have 
been nesting.   We believe it  might well be the same bird  this  year 
because of it's limited vocal repertoire in which the bird prefers 
single note calls with only infrequent phrases.  (The Baltimore Oriole 
was already confirmed for the Atlas block.)
