The Birds in Winter

It is fortuitous that at the same time when the polar vortex is once again upon us, leaving us with temperatures in the teens (F) despite abundant sunshine, I am reading a book about feeding birds and how this activity went from only in winter to all year. I learned of "The Birds at My Table: Why We Feed Wild Birds and Why It Matters" by Darryl Jones thanks to Cornell's Lab of Ornithology, which also recently published a pdf on "Winter Bird Feeding."

I have written much over the years in this blog on birds, feeding them and the harshness of winter (type "seed" into the search box in the upper left corner and you'll see them). As the pdf puts it, "If you feed birds, you’re in good company. Birding is one of North America’s favorite pastimes. A 2011 report from the U.S. Fish and Wildlife Service estimates that more than 50 million Americans provide food for wild birds."

The report then goes on to remind us all of the importance of helping the birds, what kinds of feeders help which birds the most, feeder placement and the best types of seed and suet to provide, among other considerations. Jones, meanwhile, tries to figure out why we feed wild birds and how the practice of feeding them in winter expanded to all year.

He writes: "The reality is that while wild bird feeding may be a massive enterprise with a global reach, the focus and interest of most individual feeders [the people, not the food implement] is on their own private garden. All those issues and worries may be of provound interest, but unless they affect us directly, they may seem a bit too vague or remote. On the other hand, most feeders are pleased to share their experiences or queries..." Facebook alone has many pages set up by birders in specific regions such as New Jersey and nationwide such as the American Birding Association's reports of rarities across the country.

But let's go back to bird feeding.

One of my friends puts out seed, suet and peanuts all year. She enjoys watching "her" birds from her bedroom during summer mornings when she is getting ready for work. She puts out liquid for hummingbirds every year, the feeder strategically placed near a pot of bee balm, a known hummer attractant. She used to feed squirrels, too, until they started hitting her bird feeders, including the hummingbird feeder.

I put out seed in fall, when the migrants are moving through, until early spring. In cold times I also put out suet. In midwinter I feel sure no bears will take down my feeders. Otherwise, I take all the feeders in at night. When I see the first reports of hummingbirds in New Jersey, usually after I am no longer putting out seed and suet, I put out sugar water for them. Except for the hummer feeder, which is on a shepherd's crook behind deer netting, the two feeder poles have baffles to keep the squirrels from climbing to the feeders.

My attitude is, when summer comes there are more than enough food sources for the birds and if I want to see them I can leave home for areas where they have been known to show up or have been reported. By late spring it is time to start working in the garden and I am tired of the continual feeding of birds I'd rather not see such as house sparrows. Hummers are another matter: They are hard to find in the wild unless in a garden with a lot of the blooming plants they frequent. Since deer have been known to eat these types of blooms, I don't grow them and provide sugar water instead.

Feeders in winter, before the birds started coming (Margo D. Beller)

Which way is "correct"? Both, depending on the person involved. Some people want to attract or help birds all the time, some want to help during dire conditions, such as the current polar vortex, and leave the birds to fend for themselves and their young during warmer periods. I've been feeding birds for over a decade and am not about to stop even if my feeders bring birds as well as those that feed on them. (Hawks have to eat, too, though I'd prefer it be elsewhere.)

One of the things Jones looks at is whether all this bird feeding is helping or hurting birds. His conclusion is "feeding almost always changes things," but not always in the way we expect. I see many more house finches than titmice nowadays. Cardinals and chickadees must come early to the feeders before the jays arrive and scare them off.

There's more than enough food for all in my yard, but I do wish more people in my neighborhood would join me in this relatively inexpensive bit of conservation that is easy to do and very important.

Feed the birds.

Feeding Time

Cardinal hogging the house feeder (Margo D. Beller)

Most mornings lately I have gone outside with the bird feeders around 7am when it is light but the sun hasn't risen high yet. Usually a male cardinal is sitting in the apple tree. When I prop open the screened door it starts to cheep to its mate, who cheeps back. It has figured out that when I open the door I will soon be out with the feeders - the suet on my right arm, the caged feeder in my right hand, the house feeder in my left. I go out and hang the house feeder on the first pole I pass, then walk to the other one and hang a feeder on each hook.

I go inside for the water cooler. By now the cardinal is on the house feeder but it flies off at my approach. I hang the water cooler on the pear tree and then walk back around the corner of the screened porch and close the door. Sometimes I stand outside and listen to the birds. Usually I hear white-breasted nuthatches and titmice nearby so I know they'll soon be at the feeder.

Other times I go on the porch and sit in my corner and watch the feeders.

As usual, the first birds were able to somehow communicate that food was available. But once all those birds start coming, it is interesting to see what gets to feed first and what forces them away from the feeder.

One reason I have two seed feeders out is the more open house feeder will accommodate two larger birds, one on each side. The caged feeder allows smaller birds to come into the protective cage (the cage is to protect the feeder from squirrels but I have seen small birds protected from predators), perch and eat. Chicadees and titmice will come, take a seed and leave. House finches will perch and keep eating until something, or someone, prompts them to leave.

A cardinal will sit at the house feeder and, like the smaller finches, eat until it is sated or spooked off. When a house finch or sparrow attempts to sit next to it, the cardinal will force it away. But if a comparably large bird, say a jay or a redbelly woodpecker, flies at the feeder, the cardinal departs. Jays and woodpeckers will sit a while but not as long as the thicker-billed cardinal or finch. When the big birds leave, the smaller ones can grab a bite.

Within the group, there is a pecking order. A male house finch will come to the house feeder. It might allow its mate to sit next to him but if another male house finch approaches it will fight it off if it is not the alpha bird but it will leave if the approaching bird is the alpha bird. The top bird always gets to eat. The same is true for other birds. One particularly snowy winter we had four pairs of cardinals coming to the feeder. The alpha pair always ate. If another cardinal was in the vicinity, the male would fly at it to force it away. Later, one of the others would come eat only to have the alpha male chase it off.

The only other thing I've ever seen that forces a cardinal off the feeder is if it is besieged by a lot of smaller birds that will harass it until it leaves

I don't know if this fighting would be avoided if I had many more feeders of different types out. Unfortunately, I don't have many feeders and all but one are not designed to accommodate a large bird like a cardinal.

Hummingbirds have a pecking order, too. When I had two females coming to the feeder in 2016 the more dominant one would always chase off the other. When a male showed up the alpha female would battle it, too, sometimes winning but sometimes flying off. Mind you, the sugar water feeder has several portals so they all could've fed at the same time and even brought over friends. But that's now how the bird brain operates.

Redbelly dominating the house feeder (Margo D. Beller)

The suet feeder draws woodpeckers. If the small downy is on the feeder and sees the larger hairy or redbelliy woodpecker approaching, it leaves fast. If a female downy is on the feeder and a male downy approaches, she's out of there, even if it's her mate. If two male downys are interested in the feeder, the alpha will chase the beta off, feed and then fly off, allowing the beta to eat - presuming the alpha male doesn't chase it off just because it can.

How is it determined which male or pair is the alpha and which isn't? That's another mystery better left to others to figure out.
