Over 16 chicks were banded over my predecessor's tenure. He noted the precipitous decline and even scoured surrounding areas to confirm their absence. Habitat loss and west nile virus was his conclusion as to the cause. However, important for all of us to consider: the decline happened the following season after banding began. It does coincide with larger population trends but from 1 year to the next the activity rate went from 80% to 0. In addition, following the unmanaged 2 years, activity went from 0 to 4-5 breeding pairs. Could nest managers be inadvertantly scaring birds away and/or potentially transmitting bacteria or disease?
Morning gang. So I did some research and found the backlog of former nestbox reports from the Manassas NBP network. From 1998-2000 6 boxes were available, 4 were active, 3 were successful. From 2001 - 2010 upwards of 11 boxes were available but only 1 or 2 were active or successful. Most years there were none. The network remained unmanaged in 2011 & 2012. This year however, at least 4 boxes are active of a total of 9 available. That's the best rate in over a decade!
Good morning Kestrel Klub! I'm continuing to collect as much open source, peer-reviewed academic lit, research, papers, etc. and posting in my pdf files list - If anyone is interested, they are accessible to all. I will keep posting as I find and vet them.
