This is the second year in which I recorded the first observations of the year. The following are a few of our observations:
On Sunday, March 1, 2020, I saw a pair of White-breasted Nuthatches (Sitta carolinensis) investigating a nest box I had filled with pine shavings the day before. The next day, I could see they were preparing it by removing shavings. Nuthatches are cavity nesters. They will often stash shavings and chips they remove from a cavity in the bark of the tree they are working in. I saw a lot of shavings stashed into crevices in the bark of the tree the nest box is attached to.
Kat noticed buds on the maples and oaks on Monday, March 2, 2020. One of our neighbor’s trees has large buds on it. I don’t recall seeing that large before.
It appears that as of Saturday, March 7, it is still mating season for the Eastern Gray Squirrel (Sciurus carolinensis) mating season. I saw a squirrel being chased by another in a manner suggestive of one being a female in heat and the other an interested male.
I saw and heard the first American Robin (Turdus migratorius) of the season on Tuesday, March 10. It was perched in a fruit tree adjacent to our patio.
While walking with Lizzie on Friday, March 13, we heard Red-winged Blackbirds (Agelaius phoeniceus) singing near the pond on the north side of the street.
It is that time of year again, time to empty the nest boxes. I empty the boxes in the fall on the first of October and fill them with wood shavings every spring on March 1st. Emptying and refilling them annually reduces the parasite load, thus, reducing risk for the birds.
This spring I purchased two additional nest boxes, bringing the total to five. I placed the two new nest boxes in the wooded area at the bottom of the slope at the back of our property. Additionally, I moved two of the other nest boxes so that there was greater spatial separation between all of the nest boxes.
Despite the additional nest boxes, only two were occupied this year. Again, a pair of White-breasted Nuthatches (Sitta carolinensis) took up residence in a nest box and raised a clutch of chicks. That nest box was occupied last year by a pair of nuthatches so I wonder if it is the same pair.
A nuthatch started building a nest in the other large nest box but abandoned it after a week. I don’t know if it was chased off by another nuthatch or if it moved to the nest box that was occupied this year. Come spring, I intend on moving the abandoned nest box further away from the other large nest box in hopes that I might have two nesting pair of nuthatches next year.
No Black-capped Chickadees took up residence in any of the nest boxes this year. However, I am confident a pair of House Wrens (Troglodytes aedon) occupied one of the new nest boxes located in the wooded area of our property. I didn’t observe them entering or leaving the nest box. However, they were frequently nearby, I observed them on the nest box, and they made a raucous whenever I or Lizzie were near the nest box. (Lizzie, for her part, ignored them.)
The other new nest box was occupied by two mice when I opened it up. From the looks of it, they had not been in there for long as there was no nesting materials beyond the wood chips I had filled it with in the spring. They ran off before I could take a picture or identify them. Lizzie had a fun time hunting them in the brush pile they scurried into. She caught and killed at least one. I wandered off before I saw if she caught the other one.
Three years ago, I bought a nest box and placed it on a tree near our garage. It was a nest box intended for woodpeckers and my hope was that a woodpecker would use it. Despite having plenty of woodpeckers frequenting our yard every day, they didn’t use the nest box. Instead a pair of White-breasted Nuthatches (Sitta carolinensis) took up residence in the nest box and raised a clutch of chicks.
Inspired by that family of nuthatches, I bought another nest box and placed it on a tree outside of our dining room. I was hopeful we would watch nuthatches raise a family while we enjoyed our dinner. A pair took up residence in the nest box and laid a clutch of four eggs. Unfortunately, a house sparrow (Passer domesticus) killed all the eggs, threw them from the nest box and claimed the box for itself.
When I discovered this, I was livid. Researching house sparrows, I learned they are an invasive species introduced from England and are known for taking over nest boxes and displacing native birds, in particular, blue birds.
I also learned I simply needed to narrow the opening to the nest box. House sparrows don’t tolerate openings that are 1 ¼-inch in diameter whereas native song birds such as White-breasted Nuthatches and Black-capped Chickadees have no issue with an opening that small. To displace the unwelcome occupant, I opened the access panel to the nest box, dumped the contents and tilted it at an angle so that the house sparrow could not build a nest in it. It returned daily with nesting materials but all fell out to the ground. I then purchased the appropriate constrictors and attached them to the two nest boxes I had, preventing the house sparrow from entering.
This year, much to our delight, the nuthatches came back to raise a clutch of four chicks in one of the nest boxes. It was a joy to see the chicks following the adults around from tree to tree, learning how to forage for food.
I have a yearly schedule for the nest boxes. I empty the boxes in the fall on the first of October and fill them with wood shavings every spring on March 1st. Emptying and refilling them annually reduces the parasite load, thus, reducing risk for the birds.
We now have three nest boxes, this year one was occupied a Black-capped Chickadee family and another was used by a nuthatch family. The third was too close to another box, so, it remained unoccupied. I moved it further away this fall, I hope it will to be occupied next summer. If all three boxes are occupied next year, I’ll buy another nest box and place it in the other corner of our yard. With luck, in a year or two, we’ll have four families of song birds living in our yard.
There are two bird feeders hanging under the eaves outside of our living room, one for seed and the other for suet. I placed the feeders there so that we could enjoy the coming and going of birds as fed. I recently installed a game camera to photograph the birds that frequent those feeders. While I was happy for the photographs of the birds, I was disappointed with the quality of said photographs.
American goldfinch (Spinus tristis) are beautiful summer visitors. Unlike chickadees and nuthatches, goldfinches tend to hang out on the feeder for as long as it takes to eat their fill.
White-breasted nuthatches (Sitta carolinensis), like the black-capped chickadees, are year-round visitors. Also like chickadees, nuthatches dart in for a seed and then quickly fly off. Nuthatches are the upside-down bird. They can frequently be seen walking upside down along tree trunks.
