For at least four years at the same time in late November offers bird dining at our window. In past years, the tits are not neglected our refreshments and during the winter ate five or six kilograms of seeds. But this year has changed the behavior of the birds. At the beginning of winter in our window boarded birds no more than 5-6 at a time, but for the daylight hours they are completely emptied the trough, it had to be re-filled every morning. Birds do not slide away all the time grazed on the surrounding bush, they can be easily counted, watching out the window. Pecks seeds titmouse on rowan near our second window overlooking the courtyard. Sometimes they create a plug near the feeders, hung in the mosquito nets on our windows and pushed his way into many grids of holes with their sharp claws. Then it became colder and the number of birds has increased to ten at a time. I once read that the birds do not know how to evaluate food reserves, if a bird has found a source of food, it is your behavior allows all other birds to find it too. If the feed is small, this behavior seems to be unprofitable, why call comrades if still not enough at all? But in the long term from each bird are confident that it will not pass upon detection of food, which means that if someone finds a lot of food, and then it perepadet. In the long term it is a workable model of behavior. But our titmouse as if they did not know about it))) They have always been just enough to peck seeds and all have not fought because of them ...
And then came the cold ... Since early January, temperatures dropped at times to -15 - -17 ° C, and birds on our window was very small. When warmed, and the thaw began, our steel window fly one or two tits and not every day. Seeds remain intact and more we do not fill the feeder again every morning. This is the first time in four winter.
We assumed that the birds could not survive the cold, but then it occurred to us that now in the big cities like Moscow birds began to wait another danger. The fact is that now with the snow fight mainly strewing his immoderate amount of anti-icing agent. And even in fairly severe frost on the pavements can see puddles. But it's not just melt water, this reagent solution ... What if the birds are trying to drink it and die ???
A few years ago, Russia has another environmental holiday - Sinichkin day. It was created on the initiative of Russian Bird Conservation Union and is celebrated on 12 of November. On this day, residents of different localities of the country are preparing for the meeting, "The Winter Guest" - birds that remain to winter in our area: titmice, goldfinches, bullfinches, jays, redpolls, waxwings. People harvested for their feeding, including "Sinichkina goodies": unsalted bacon, roasted pumpkin seeds, sunflower or peanut - make and hang the feeder. Despite the fact that as an ecological feast day is celebrated Sinichkin relatively recently, its history goes back to the distant past. In the folk calendar is listed as November 12 Day of Remembrance of the Orthodox St. Zinovy Sinichnika. According to national signs, it was at this time tit, anticipating ambulances cold, flew out of the woods close to human habitation and waited for help from people.
Every year for the past four years, as soon as it is cold enough, usually in the second half of October, we open our season on the aft window. Every year we do a simple and light structure made of laminated cardboard package with a slotted hole and hung it to the nail, which is driven into the top of the window frame. Now the most important thing every day without holidays and weekends at the same time in the morning to fill the bird feeder seeds.
Why is it important not to miss a single day? Because the bird once found out where they will feed, will fly to the feeder every day and expect to see food. If food is not, and the birds prozhdut long time, then they can not catch enough of the short winter day. Birds looking for food only at the light as soon as it gets dark, they arranged for the night. Hungry bird can not survive the long cold nights.
On the other hand, if you make a very large bird feeder and three times a day to fill it up to the top seeds, the birds stop to look at all their legitimate food - wintering od bark insects. Seeds - this is a very fatty and high-calorie foods that can cause obesity, birds, and also eventually destroy them. Let's not forget that not all people know how to feed the birds, so that they can offer them a roasted seeds and nuts, salted crackers, wheat, moldy bread ... All this is pure poison for the birds!
So the correct way to feed the birds seeds (seeds of grasses, dried berries - depending on what birds you expect to trough), to feed every day in the morning, not overfeeding, emptying the feeder to the birds went on their own hunt. Then they will examine and get rid of pests of all the trees in your backyard, in your garden or near the school. And you can help birds survive the harsh winter!
