[obol] Re: swallow nestbox deaths

[Bobbett Pierce]

In regard to yellowjackets feeding on dead birds in nestbox, I experienced a 
nestbox of bird deaths with swallows, too, only ours were violet-green 
instead of tree swallows.  An adult v-g swallow and three partially grown 
but feathered young all found dead.  I blame English sparrows for killing 
them.  I was having some problems keeping the sparrows from stealing the box 
from the swallows, when we left for a week on vacation.  The swallows were 
OK when we left.  When we got back the swallows were gone, but the English 
sparrows weren't around the box, either.  I assumed the young had fledged, 
and only discovered the dead family when I took down the box to clean it.
