On the last day of April this robin, perhaps a male, may be scouting out a May nest building site. Robins are one of our earliest birds to nest. The male arrives first and picks out an area an acre in size. When the females arrive and join their mates the final size of the mating area is reduced to about 1/3 of an acre. The females will do most of the building with the male helping bring construction materials to the site. The nest will be built in a location such as that shown in this photo and takes from 2 to 6 days to build. Stay tuned to see if this scouting excursion turns out to be an actual building site - if so more photos will follow.
