Re: Report of dead bluebirds by Alyssa Salomon. 

I live in a very rural area near Farmville. After reading your report, I 
checked my boxes today and found two male bluebirds dead (each in seperate 
boxes).  Another was found on the back deck. There were no external marks to 
indicate dying due to predator action. Although bluebirds will tend to crowd 
into a nesting box on cold nights, no active bluebirds have been observed 
subsequent to the two snows.

First thought:  I would think that a die-off might well be related to the 
unusually cold conditions. During our recent snows, two bluebirds were observed 
feeding at suet blocks, along with other species that are not commonly seen 
around house. In past years, I have taken photographs of bluebirds showing them 
consuming berries from wild sumac bushes. They have also been observed visiting 
a hanging feeder filled with black-oil sunflower seeds that had been liberally 
sprinkled with freeze dried meal worms. So from field observations, supported 
by photographic documentation, I do know bluebirds eat seeds. Each observation 
(and photographs taken) occurred during snow, ice and unusually cold 
conditions. Record cold conditions prevailed this past month.

The questions are:  
1. Was a source of wild seeds or supplemental feed available?
2. Was this apparent die-off due to the frigid temperatures
3. Did pathology have a role?

If more reports come in from a wide radius, concerned bluebird hosts might 
consider delaying the cleaning out of nesting debris from the previous season. 
This would provide addition insulation against the cold.
Should numerous reports continue to come in, it might be an issue for Audubon 
to explore.
