Budding Maple Trees

Maples (Acer) are one of the earliest plants in Minnesota to bloom in the spring and, as a result, are an important source of food for pollinating insects.

Because the flowers are normally high up in the tree, we don’t see the flowers. On our evening walk, I was excited to see that our neighbor’s maple tree was in bloom at a level I could actually photograph.

Siberian Squill (Scilla siberica)

One of the first plants to bloom in Spring is Siberian Squill (Minnesota Wildflowers – Scilla siberica). It’s pretty flower and is scattered all over our yard.

Unfortunately, it is considered an invasive species. I have no hope of eliminating it from our property. To do so would require extensive remediation for which I have neither the time, nor money, nor the energy.

Mallards (Anas platyrhynchos)

Every Spring a pair of mallards (Anas platyrhynchos) temporarily makes our yard their home. There is a small creek at the bottom of hill in our backyard. In the spring it has sufficient water flowing in it for mallards to float around on it. It usually dries up at some point in the summer but mallards find it a comfortable place to hang out in for a few weeks.

The mallards will often come up to the top of the hill and wander around near our house and garage. If I’m lucky, I’ll get a photograph or two of them. Having keen eyesight, they are quick to spot me, even when I carefully peak through a window.

On Thursday, I saw a hen and drake eating corn near one of our critter feeding stations. I quickly grabbed my phone but they, having seen me, ambled away before I could get a good closeup photograph of them.

First Observations of 2020, Part 1

This is the second year in which I recorded the first observations of the year. The following are a few of our observations:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

Bald Eagle (Haliaeetus leucocephalus)

The sound of dogs barking alerted Lizzie and I that something was afoot in the neighborhood. It is not unusual there are dogs barking in our neighborhood but something about the barking drew our attention.

While I listened to the barks trying to determine the reason for the upset, Lizzie let out a low growl which immediately grabbed my attention. Lizzie rarely vocalizes and very rarily growls. To my surprise, looking to where she was staring, thirty feet away, I saw a bald eagle (Haliaeetus leucocephalus). I regularly see them flying overhead but this was the first I have seen in our yard.

Grabbing the binoculars, I saw it had been eating something. I could see blood in the snow and nearby what appeared to be the remains of an animal.

After the eagle flew off, Lizzie and I investigated the site, where we found tracks, blood, fur, and various parts of an animal.

Nest Boxes

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.

Virginia Opossum (Didelphis virginiana)

A Virginia opossum (Didelphis virginiana) has been a regular night time visitor. Other than a stray cat, it is the most frequent visitor to our night time yard.

From the images captured on the game cameras, it appears the opossum is searching for food under the shrubs in the back yard. It has been going there nearly every night for the last several weeks. Maybe it is finding grubs and worms. When I’ve looked in that area I haven’t found much of anything else.

I hope it keeps a low profile during the day because I don’t want Lizzie finding it. Two years ago, Lizzie found an opossum in our yard. When she attacked it, it played ‘possum, looking for all intents and purposes to be dead, releasing a foul-smelling liquid in the process. Lizzie, being a dog, promptly rolled in it.

Because the door to our house was wide open, I was concerned Lizzie would enter the house, fouling it with the her new “perfume”. I let her mess with the “dead” opossum while I stealthily made my way back to the open door. As soon as I closed it to prevent her ingress, I called her to me, ran to the exterior water faucet, turned it on wide open, and grabbed the attached hose. Grabbing her by the collar as soon as she got within reach, I hosed her down. Lizzie, disliking baths, tried to escape but I kept a firm grip on her until I had thoroughly rinsed her. To this day, she watches me warily any time I use the hose.

First Observations of 2019, Part 2

This is a follow up to my First Observations of 2019 post from May.

On Sunday, June 7, around 4 in the afternoon, we heard the first cicadas of 2019. I call cicadas the “hot bugs” because they are the most active when the summer becomes hot. While the temperatures were pleasant on Sunday, I knew we were getting into the hot time of year when I heard the cicadas .
