Winter Blues

There is nothing scarier, for me, than seeing a man who tends to stay up into early hours of the morning holed up in bed, huddling under the quilts shivering, at 9pm.

But that was because MH was reacting to this intense period of sub-normal cold that has been afflicting New Jersey and the rest of the eastern half of the country.

When you hear of people dying in Tennessee from hypothermia or getting into accidents because they are driving fast on ice-covered roads, you know something is not normal.

When it is warmer in Anchorage, Alaska, than it is in Morris County, New Jersey, something is not normal.

When the New York Times devotes space to an article in its science section on what to call people who do not believe we have climate change or global warming or whatever it's hip to call it at the moment, something is not normal.

We know about the winter blues, that depressed feeling you get because it seems to be so dark for so much of the day. SAD is the acroynm, and it is appropriate. But this is beyond SAD.

Here we are at the end of February, two months on from the shortest day of the year, the first day of winter. There is more light during the day, starting earlier in the morning. Cardinals, titmice and other birds are singing, calling or drumming out territorial warnings based on the length of daylight, not the temperature.

We humans also sense that maybe spring is just around the corner. But for the last month, it has rarely been above freezing and my area is still blanketed by the snow from several storms that fell earlier in February. I can't keep up with the birds (and squirrels) hitting the feeders for food. I have to bundle up and put on my boots to refill feeders on the coldest mornings, and handling metal feeders is no fun even with gloves on.

It is hard just to take a walk - how warm should I dress? Should I wear boots or can I get away with shoes? Is the neighbors' sidewalks shoveled out? What is the windchill? I am sure got a lot of traffic over the past month.

Back to MH. Today he told me he just couldn't handle the cold - not the fact we keep thermostat at 66 degrees or so to save money but the cold in general. He said he felt the need to go upstairs, lie down and pull up the covers.

In effect, he went into temporary hibernation, just like the bears, chipmunks and many other woodland creatures.
We humans still have that instinct, to sleep through those times of intense cold and long darkness. We tend to eat more and exercise less and eat more "warm" meals with starches than "cold" meals of leafy salad greens. We eat too much, get lethargic and, at least in my case, sit in a chair near the heat register and let the sun shine through my windows to warm me.

So while MH's behavior was unusual for him, it actually makes some form of sense.

So does the reason for the sub-normal cold afflicting us this year as it did last year. Last year we learned about the "polar vortex" and how the air that normally flows over the north pole got bent out of shape, if you will, because of shifting wind patterns.

Now we are learning about melting polar seas and how that warming - that global warming - has pushed down the jet stream over the eastern half of this country while the western half has gotten next to no snow and is warmer than usual, which means another summer of drought. Cold comfort to my friends in New England buried under feet of snow right now.

Global warming, climate change - call it what you will, it is there and it is real. It is creating extreme weather. It is putting ice in the deep south and creating hurricane-force winds in deep winter. It created several feet of snow in one Buffalo snowstorm this winter and has created dangerous windchills over New Jersey four times in the last two weeks.

This is not something we can get under the covers to avoid. But I fear it may already be too late to repair the damage.

Backyard Feeder Drama

This weekend has not only been Presidents Day weekend and Valentine's Day weekend but the weekend of the Great Backyard Bird Count run by, among others, the Audubon Society and Cornell. These counts are useful as a way of getting the average person as well as the avid birdwatcher involved in reporting what they see and how many, which helps the scientists get an idea of what species are increasing and which are on the decline.

This particular day, Sunday, Feb. 15, the wind has been howling and I've had to go out twice to re-set a feeder in danger of being blown off the pole. I came downstairs at 7:30 a.m. and the birds were already all over the 4 feeders I left out despite the risk of wind. It is wicked cold out, wind chills in the minus numbers and even the enclosed porch's thermometer is showing me 10 degrees.

In short, it's cold and the birds gotta eat to survive.

The early risers are there - cardinals, chickadees, titmice - and a few surprises including a pair of American goldfinches and a Carolina wren that nestled inside the house feeder as the wind rocked it like a cradle. When things calmed it flew to the suet feeder and took advantage of the pounding a larger hairy woodpecker had given the near-frozen fat to take a few nibbles before flying off. I like Carolina wrens and if I had been outside I am sure I'd have heard it singing from somewhere nearby.

But I did not go outside. And at 8am, just as a cloud of house sparrows and house finches descended to push off the birds I do like, there was a gust of wind and a sudden large bird in the yard I just knew to be an accipiter and all the birds scattered. The bird flew to a low branch, giving me a perfect view of it. I saw it was an adult (gray feathers, red breast), male (smaller than the female) sharp-shinned hawk with its rounded head and square tail.

Accipiters are the most feared birds in this area. The sharpy and its larger cousin, the Cooper's hawk, are lightning fast and agile enough to fly between trees in a forest, going after birds, squirrels and other smaller animals. I have seen sharpys fly out of a bush. They seem to come from nowhere (unlike the larger red-tailed hawk, a buteo, which either hovers in the air or sits atop a pole or tree before dropping down to grab prey in an open area like a highway).

The sharpy sat for 10 minutes before catching another gust of wind out of my backyard. It took another 20 minutes for any birds to return to the feeders, and I was not surprised they were the intrepid chickadees and their cousins the titmice.

When I told MH about the sharpy he reminded me what it says in one of my reference guides, "Birds at Your Feeder," when it comes to sharp-shins and Cooper's - they like birds at your feeder.

We have hawks fly through at all times of the year, going after birds, squirrels and chipmunks. We've had a small flock of turkey vultures that somehow found a frozen rabbit carcass in a corner of my yard. We've had broadwing hawks, red-tails and even a juvenile northern goshawk, the largest of the accipiters, that somehow found its way to a low branch in my backyard for a day.

I find the accipiters most interesting. When they are young they are brown, streaky and not very good at catching prey. We've seen several near-misses over the years including the time an American tree sparrow flew out of our caged feeder just as a juvenile Cooper's hit it from the other side. It sat atop the feeder stunned, and I took a picture. I've seen juvenile Coopers on a branch on one side of a tree trunk trying to grab at a squirrel on the other side. It would be funny to watch if it wasn't a life and death struggle. The hawk wants to eat, the squirrel wants to live.

But accipiters have to learn fast if they want to survive and by the time the streaked breast goes red and the brown feathers turn gray they know how to hunt very well - unfortunately for the junco and the chickadee and the mourning doves I've seen picked off in the yard over the years.

The only thing that kept today's sharp-shinned hawk from catching any of the many birds at my feeders was that sharp wind blowing it off course. Today, the little birds got away. Tomorrow?

I've no doubt that sharpy found something in another yard to fill its crop and allow it to live to hunt another day.
