Last week, during a time when the weather seemed ‘unfit for man nor beast’ and while Rick was working on reglazing some barn windows…working inside the barn not out… two bluebirds showed up to feed on the dead flies trapped along the window sill. Bluebirds! Yes, really, a pair of bluebirds! Well, this is odd and it meant two things. First, call George. George is the retired vet in our area and also an avid birder. George is the only other person we know besides my father who has a great love and appreciation for bluebirds. When my dad was alive he and George would often consult one another with regard to the comings and goings of the bluebirds. This was great for my dad, (who by the way also wore the covers off of every sequel to ‘All Creatures Great And Small’), and his being able to converse with someone who was a vet and also kept track of this areas bluebird migration.
George filled us in on some of the habits of bluebirds and then (secondly) we did some research of our own. My dad would be very happy to know we did this.
So, bluebirds don’t always migrate. When they do leave the frozen northeast, they head for places as far as Texas but may only travel as far as they need to find a food source. Their winter fare is mostly berries. It is true that some hardy bluebirds do brave the winter here, apparently making their way through by eating berries and fruit from various trees and shrubs. They’ll also feast on dead and frozen bugs, like the bluebirds who were eating frozen flies along the window sill at the farm. Not an easy choice I would say, but not as uncommon as you’d think. When not nesting they move in flocks and beginning in the Fall, these groups of bluebirds start meandering south following food sources. But, some do stay. At least these two did. In the winter, if they remain in a frigid climate, like Maine, they will find shelter in a hollow tree. Often as many birds that can fit inside that hollow will do so creating warmth in numbers. Unfortunately, there has been a significant decline in bluebird populations over the last several decades. Most of this is due to habitat loss, insecticides, and the introduction of starlings and house sparrows that out-compete them for food and shelter. This makes me even prouder of my Dad ( and you, too, George!) for taking such an interest in the well being of our bluebird population.
When my Dad passed away, my mom forwarded some of his books to me. Mostly because my dad and I loved many of the same things…nature, farming, and food ( he was known to drive 100’s of miles for a good piece of pie…who wouldn’t!). In one of the books that was passed along, ‘Song And Garden Birds Of North America’ I found pages of my Dad’s bluebird notes folded up in the back. He had been tracking the bluebirds (and building them boxes) since 1966! His last entry was 2002, just two years before he passed away. I love that my dad did this, I love seeing his carefully handwritten notes, excerpts like “A pair of Bluebirds arrived, they did not nest until April 2nd or 3rd. The female laid a clutch of five eggs”. This was written in 1971. On another account, in 1969, he wrote this “A pair of Bluebirds arrived and soon nested in the same bird box of previous years. Also, I noticed the presence of a house wren. Which seem to be a menace to the bluebirds. By the sound advice of a friend, Mrs.Trudy Smith, who is quite familiar with all birds, I netted the female house wren who had nested in one of the bluebird boxes. With somewhat of a struggle, I might add. Mrs. Smith then took the house wren, banded it, and took it to the Harkness Estate in Waterford.The bluebirds had two eggs in the box at the time of the house wren departure. The female bluebird has been in the nest two days. So I think she may have laid a clutch of four eggs”.
In honor of my Dad and all other bird watchers, we’ll keep a close eye on the two bluebirds that have stayed. We’ll hope that they brave the winter so that this spring when the first hatch of insects descends upon us, they’ll be swooping through the fields having their fill.

Perhaps you have the perfect location for some nesting boxes or maybe you’d just like to find out a little more about those birds my Dad so carefully thought of throughout his years.
