Today I checked all 4 of my nestboxes. There are two groups of two each. The two groups are about 350 ft apart. The group where I saw a male house sparrow 2 days ago had a male house sparrow sitting on top of it again. There was the same nest in the box but no eggs. The other box was empty. In the other group I saw a tree swallow fly out of the box and a little while later a tree swallow flew into the box. I thought that meant this was an active tree swallow nest and I did not disturb it. The second box in this group had a dead tree swallow sitting on a nest. I removed the nest with the tree swallow and on the floor of the nestbox were about 20 wriggling insects.
What is going on here? There are 2 photos of this on my ebird checklist: CHECKLIST S110613362 Thanks, Fred Kardon -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://firstname.lastname@example.org/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
