I don't think the low productivity did was restricted to just Purple
Martins. The MAPS (Monitoring Avian Productivity and Survivorship program)
station on Bainbridge this year recorded the lowest number of juveniles this
year in five years of study. 2002 was also a year of MAPS on Bainbridge,
and it was the second lowest production year for juveniles.



Barred Owls, on the other hand, seemed to do well..

Subject: [Tweeters] Cause of local 2008 Purple Martin deaths?



Talking to Rich Siegrist here on Vashon, he found 9 dead adults in the boxes
he has set up over the last 15 years. Last year there were 71 pairs here,
this year 14. Checking the Office of the Washington State Climatologist
website, this spring's temperatures were relatively cold. However, the
spring of 2002 was also equally cool, yet Rich doesn't have the same sort of
dip in his records.



Is more than the weather going on with the martin population or was there
something particular about this year that made a difference?
