2009 Season Ends

And so another season ends. Thanks to everyone who helped out! This was a pretty quiet and undramatic nesting season, which I am thankful for. We had very few accidents and fatalities — hugely thankful for that. Those of us who have grown fond of our MCC jailbirds experienced some letdown when Herc and Max didn’t produce any young for the first time since at least 2004. We’ll have to keep our fingers crossed for next year.

Anyway, without further ado, here’s the final wrap-up from Mary Hennen (edited):
