US songbirds getting smaller, possibly as a result of climate change

[Ian May <>]

C'mon Laurie!   It's not April 1 yet.   Didn't we read last year that 
birds forced up the mountains by higher temperatures are becoming 
smaller too.  If this keeps going, crows will be smaller than blow flies.
Are these climate change findings an example of robust peer reviewed 
science or just quotes from grey literature?

Regards


Ian
