Dawn Chorus, With Junco

It is a cold dawn with slight fog as I stand on my back patio, listening. There are many robins singing, the occasional high peal of a cardinal. They are greeting the day in their own ways, proclaiming "I am here, this is my territory, stay away unless you are a potential mate."

Robins are the early birds that catch the worms, but there are others in this dawn chorus that join in as more daylight comes. More cardinals, the "here, here" of a titmouse, the "oh Sam Peabody, Peabody, Peabody" of a white-throated sparrow now in breeding colors (his throat and "eyebrows" are a very bright white and you can see the yellow close to the eyes, an area known as the lores).

In the old days, when I walked early in the morning to the train to take me to work, I would listen to the birdsong. Some birds I could easily recognize, others I would come to learn over the course of a decade. The chatter of goldfinches, the "tea kettle, tea kettle" of a Carolina wren and the cascading warble of its smaller relative, the house wren. The "hey sweetie" of a black-capped chickadee or the raucaus "thief!" of the blue jay. It took years of searching trees and walking through the woods to learn which calls were made by which bird.

Now, standing still in the growing light, I hear Canada geese, the high-pitched squeal of a red-bellied woodpecker, the three-note "tzee-tzee-tzee" of a golden-crowned kinglet, the drumming against four different trees by woodpeckers proclaiming their territories. Here are the mourning dove, the fish crow, the larger American crow and the rattle of cowbirds. The slight differences in call between a downy woodpecker and the larger, nearly identical hairy woodpecker.

Once in a while there is something unusual -- a sharp-shinned hawk flap-flap-soaring overhead, a raven's guttural croak, the high-pitched "hank" of a white-breasted nuthatch. The longer I stand outside, the longer I hear another soloist come to the foreground of this chorus. For me it ends as I am going inside to warm up and get some coffee and a flicker does its long laughing call.

Spring is my favorite time of the year. The birds are noisier as they start looking for a suitable nest site and a mate. The migrants are passing through my area, heading north from their wintering grounds. Ruby-throated hummingbirds have been reported as far north as New Jersey, despite our unusually cold March and April weather. When the instinct says go, you go.

Depending on where you are located, you will hear different birds calling in the dawn or at dusk. My patch is a suburban town in New Jersey. In a few weeks, if I'm lucky, I might hear the softer songs, clicks and buzzes of the warblers and other migrant birds foraging in the treetops as the first rays of the rising sun hit that area. There are many songs I still can't identify, even after all these years.

One of the interesting "problems" I have is telling the difference between four different birds whose songs are very similar. What I heard the other morning as part of the dawn chorus was a small black and white sparrow with a pink bill called a junco or, to give it its formal name, a dark-eyed junco. This is a winter visitor, and in my part of the country it is only the male birds hanging around. The browner females stay farther to the south. The idea, I think, is the males can get north and find the best territories faster if they stay farther north. So they and the white-throats come to the feeders in winter and are soon replaced by summer visitors including the catbird and the chipping sparrow.

The junco's call is soft, high in pitch and musical. The chipping sparrow will call more loudly, longer and the call is not as musical. Some refer to it as "dry." To me, and this dates me, it sounds like a person using two fingers to tap tap tap on a manual typewriter keyboard, kind of mechanical. As noted, the chippy arrives around the time the junco is making ready to leave and you'll often hear their calls during that time.

There are two other summer visitors with similar musical calls, so I have to work my memory a little harder to remember them. I don't have many pines growing around my area and I don't live near a swamp, so I have to travel elsewhere to hear pine warblers or swamp sparrows. Pine warbler song is high in pitch and very sweetly musical. The ornithologists at Cornell describe the swamp sparrow call as "a slow trill consisting of two or more pitches repeatedly sung essentially at the same time." To me it sounds like a chippy or a junco.

As problems go, trying to remember the different songs of four birds is a minor but enjoyable challenge.
