Cornell Herons Highlights 2014
3 October 2014
‘Dad’ Great Blue Heron with his missing toe has been nesting on Sapsucker Woods Pond raising a family each year since 2009. Unfortunately, the nest was blown down during high winds in 2014. That did not stop ‘Dad’ from visiting the pond regularly and continuing to claim it as his own. We also believe he may have raised a family successfully nearby as he was seen with juvenile herons over the summer. Fingers crossed that he decides to return next year to construct a new nest.
