When You Know Migration Is Truly Over

As I write, October is nearly over. We have had nearly a month without rain in New Jersey, where I live, and the shriveled leaves rain down with every puff of wind. We had lovely color for a while but then the temperature, which had dropped, started rising again. Now, Halloween might be 80 degrees F, a new record.

Every day I check the lists to see what other birders have found and also the interactive "Bird Migration Forecast" map that uses the information picked up by the nation's radar system to track bird movement. Lately, movement has been light.

So in my head I know this year's southbound migration is just about over. But it was still a jolt to visit an area I only recently discovered to be a good place for a variety of sparrows, warblers and other birds needing a place to rest and where they can feed on the weed seeds and the fruits on assorted vines. 

This weedy area is in the Central Park of Morris County, which I still refer to as Greystone for the former mental hospital that moved up the road. The site is 5 minutes from my house, making it very convenient to visit daily. It is a very large piece of property and one can find birds, deer, even foxes if you hike early in the morning before the dog walkers and runners show up.

This particular area I'm mentioning consists of two drainage ditches located behind the playgrounds. These ditches became overgrown with weeds, as open areas like this will do. One of the ditches also has small trees in it, and that made a difference to what I now relate.

I came to the area today for the first time in a week. As I walked over from where I parked I saw half of what I called the "sparrow bowl," was gone - completely mowed down. The other half, where the trees are growing, was left basically alone except for the mowing down of ragweed at the edge. With my binoculars I looked up the path at nearby areas where I discovered more birds would hide in the ragweed. All gone.

Logically, I can understand why this county park would want to mow down ragweed. I don't like it in my yard either. This area of the park gets a lot of foot traffic between the dog walkers and the cross-country runners, with a birder like me showing up here and there.

Emotionally, I was ready to throw up.

There are still plenty of weeds near where I was standing in the park and in the fields beyond, but the only birds I heard or saw today were the ones I'd expect to hang around during the winter including juncos, various woodpeckers, jays.

[UPDATE: Between the time of this post and today, Nov. 3, the weeds in the second drainage area were cut down. The trees were left standing. I found late migrants in a field down the hill where they can hide among the dried goldenrod.]

I was reminded of when I worked in Jersey City, on the waterfront. There were plenty of open, empty lots filled with weeds. During migration I'd find plenty of birds, including the types others reported from more typical migrant hotspots such as Central Park in New York City. But soon "development" did away with those open lots, and with them the birds.

Many weedy areas in parks and vacant lots are important stopovers for birds on the move, but most people don't look at weeds that way. What was a nearby bird paradise for me (and the birds) was just so much wasted land to the Jersey City "developers" and, I realize, those who want Greystone used by everyone, birders and nonbirders alike. So once again something has changed, and not for the better.

In this particular area, at least, migration is over. I'll have to look elsewhere farther afield and hope to find this paradise restored next year.
