The Calendar Says Spring

March 21, 2018 (Walk # 1061)

This was my first walk after the vernal equinox and I was looking for signs of spring. I found a few, but winter is not over. A few observations from today:

The river water level is quite low for March. I use the extent of visible sycamore tree roots on the right for comparison purposes.

One advantage to the nature walker of the lower water level is that there is more mud along the river edge, the area between the sides of the bank and the water. More mud means more mammal tracks and, at least for me, tracks in mud are usually easier to read than tracks in snow.

Here is an example.

I circled two obviously different tracks here. The one in purple is typical of a raccoon and the one in red was made by a canine, probably a coyote.

Robins are abundant in the park now and, in this time between winter and spring, are exhibiting both winter and spring behaviors. Many are feeding on the ground, but others are still foraging for fruit and seeds, as they do in winter.

I posted about sumac seed clusters last December, about how long they persist. Some of last year’s seeds are still present now and today both chickadees and robins were feeding on them.

The number of bird species seen today – 18 – is the highest so far in 2018. A couple of these are winter visitors that have not yet returned north: Dark-eyed Juncos and American Tree Sparrow.

There are a few signs of spring. Some birds are pairing off, preparatory to breeding season. One Downy Woodpecker now usually means another is very close nearby. Canada Goose is one of the earliest birds to nest along the Rouge River and this pair appears to be getting in the mood.

While the park still has the brown winter look, it is possible to find a little bit of new green. As in home gardens, the first plants to emerge from the ground are those that grow from bulbs or rhizomes. I was pleased to see that a native species of marsh iris is back again this year.

Today’s observations indicate that this March is both colder and drier than normal. I anticipate rapid changes in the park as the weather warms.
