["David and Gloria Patterson" <dgpatterson@xxxxxxxxxxxx>]

Carolina Wrens nest on a bathroom window sill, outside of the screen and inside 
the hinged window.  The current nest had four eggs.  Before the eggs hatched we 
found one of the eggs on the window sill, with a 2 mm hole punched in the 
shell.*  We had a House Wren singing vigorously that day, and suspected it.
We check the nest from time to time with a dental mirror.  One egg hatched at 
least a few days before the other two.  Today there were two young of very 
different sizes, and no sign of the other egg.

The larger one weighed about 40 grams, the smaller one about 8 grams.  The 
primaries on the larger one appear full length and the last 5mm or so are out 
of the sheaths.

We are curious.  Is such a large difference in size unusual?  Photo available 
if you are interested.

*David set the punctured egg on the picnic table where we were eating lunch.  
Gloria absent-mindedly picked it up and put it in her mouth and started to chew 
it!   She may be the only person in recent history to eat a raw Carolina Wren 
egg.  In the interest of science she reports that it did not taste good, and 
she spit it out right away.
