This small woodpecker (Sphyrapicus varius) is a common winter migrant to the region. As its name suggests it does feed on sap and is often found on exuding trees. This was on a pine in the Ecosur grounds and seemed to be picking insects out of the resin. The bird can remain still for long periods of time, but this unfortunately makes it a prime target for young children with catapults. I have found several dead individuals, obviously hit by stones during my time here.
