After several weeks of following the multiple Cerulean Warblers at Quabbin Park  I was finally able to confirm breeding again for this year.  The first Cerulean Warbler arrived on May 8th and by the next day I had three singing males and one was banded on May 12th (I believe this was original male as the area it started singing in is the same area it has stayed in throughout).  Multiple males continued through May and on June 11th I maxed out the number of singing males at four (with the only banded individual being the one banded this year).  I have been trying in vain to confirm breeding until today.  Following some birding earlier in the morning in Ware and Hardwick I made my way over to Quabbin Park around 8AM.  With somewhat limited time as I had to get some stuff done at home and get Wilson a walk before it got too hot I concentrated on trying to track down some of the Cerulean Warblers.  I have had just one very sporadically singing male during my previous two visits to the area in the past week and a few days ago I was able to get eyes on the banded male.  I walked the area and did not hear any Cerulean Warbler song at all and with calm conditions I'm sure I would have heard even a distantly singing individual.  As I was scanning the area where the banded male has consistently been I caught sight of a female Cerulean Warbler...my first in the park for the year.  I watched her forage for a bit and eventually she had a mouthful of food and disappeared to near the top of a large maple.  She repeated this behavior for at least the next thirty minutes I was watching her. I briefly caught sight of the banded male but I never saw him carrying food or approaching the probable nest location.  Despite trying many different angles to try to find the nest I had no luck but I'm quite certain there is a nest with nestlings in the tree in question.  I'll try again to get views of the nest tomorrow perhaps.  Last year I also confirmed breeding of the species with the sighting of a fledgling in early July and I highly suspect breeding has occurred in a few years previous to last years confirmation.

My stops prior to going to Quabbin Park found lots of evidence of breeding warblers with fledglings around and multiple adults of numerous species carrying food to feed nestlings or fledglings.
