I had somewhat of a surprise this morning when I checked one of my PVC houses and found a chickadee nest containing the start of a clutch with 4 eggs. This particular house has been used by chickadees before but has never had eggs quite this early in past years. However what I found to be extremely interesting (and this might be old news to many) was that the female chickadee clearly covers her incomplete clutch when she leaves the nest. When I first looked in the house and down on the nest I could clearly see there was no visible nest cup. I was curious then carefully separated and lifted what almost looked like a "flap" of rabbit fur and moss which then exposed the 4 eggs. I had no clue chickadees exhibited this type of behavior and now curious if any other Passerines do the same? Pretty intelligent I'd say since it clearly hides the eggs from potential predators. Anyone else ever see this before? Again probably old news but a first for me and thought it was worth sharing. Regards, Rick Pertile Sawyer County p.s. Watched a tree swallow busy nest building in a Peterson house on Saturday. I can't recall for sure but think this is the earliest ever for me in Sawyer county or very close to it. I know I have another record documented somewhere that was also very early but don't think it was on or before this date of 4/14. #################### You received this email because you are subscribed to the Wisconsin Birding Network (Wisbirdn).
