I've been working in the same place for many years,but just 2 days ago I noticed something that I have seen before but I never wonder why.. through the window I can see a park most of the days birds flying or feeding on the ground...chasing each other.making noise..etc.. but 2 days ago  everything was very quiet no a bird on the ground. they were on the trees although it was 10am..  at that moment I began wondering why is it?  and I recalled having seen the same thing before.  Could you please someone could tell me if they have witness a similar event wherever you are.  and why is it?  There must be something that on some specific days affects the bird behaviour

On extremely cold days many birds will roost to conserve heat. If they take to the air they expose their underwings and bodies, and the short insulating feathers under the flight feathers are exposed to the cold air, so they no longer provide adequate insulation.

I was fox hunting with my ex wife's uncle one night. It was a clear sky and stars everywhere. We were walking through a meadowfield and all of a sudden everything lit up around us like it was daylight. As quick as it happened it was over. We looked at each other startled and still to this day don't have answers. There was no noise and nothing in the sky.

Oh' they can definitely distinguish people. Anyone that owns a bird can tell you that. If someone besides me gets near my parrot, watch out!

Check if the bird is caring for chicks.  In some species male or female sit on top of their chicks to protect them from predators, while his/her mate brings food.  Some species alternate .  If not, it might be wounded, hatching a dead egg or another number of reasons.  Probably caring for chicks though.

This is sybil's first question. Try and give her a good answer.\nI'm sure someone out there has a good idea of what it could be.\nAnybody got a bird book? Cause now I really want to know too.

Whats nice about the world is that if a hummingbird dies, generally, another will replace it, and so the cirle of life goes on.  Unless you plan on tagging the hummingbirds for surveillance / observation, I dont think you'll notice any missing hummingbirds.

I havent had an encounter.... but I have seen one. It was hanging over a highway at night.We drove directly under it, and it was no higher up than a treetop. The object was triangular in shape, with rounded corners. There were colored lights along the inside of the triangle. It made no noise as we went under it, and on the way home, my friend said it wasnt there. For those of you that answered my question about ufo's, whether you believe me or not, I was not on anything, and wasnt drinking. I know what I saw.

Gods not doing it, the birds are because they are hungry. They are hungry because the old man sold the land behind his house to the city folk who tore down the birds homes and the wild berry trees where they used to eat, to build a new strip mall. Thats what I heard anyways :/

When hunting ground birds, a dog normally runs out in front of the hunters.  When the dog goes on point, the hunters get an idea of whee the birds are (in this case it was a covey of quail).  The hunters move forward and at some point the prey is flushed (they startle out of their nests and fly away, toward, up, all directions, although usually away.  Usually when hunting ground birds two hunters go with one dog, but a line could be used....  \n\nThe dangerous part is when a bird flies back through the shooting line.  The shooter have to be disciplined enough not to shoot outside of their arc, in order to avoid the other hunters.  Now the arc changes slightly as the shooting line follows the outriders and the dogs.  If someone is out of line or a bird flushes toward a hunter, there is a risk of getting shot.  In this case, the man who was shot was out ahead and to one side.  \n\nWhen one tracks a ground bird, one tracks from where the bird flushes and aims a bit ahead with the shotgun.  So the muzzle of the gun moves from down to up.  It is easy to get hit when hunting quail, pheasant, partridge, etc.  Safety rules must be observed and the guide has to keep track of where everyone is.  \n\nIf you hunt birds you are going to catch some bird shot from time to time, I have been hit twice, although at longer range and with fewer pellets.  The more you hunt, the more likely you will get hit.  Other factors influence as well.  This incident happened late in the day when people were tired and the sun was low.  This is when a lot of accidents happen?  Hope this helps.

There was a meteor shower the last few days, but those happen about once a month or so, with varying intensities, so nothing new there really.  I think there's no reason to think there's a correlation between your animal's behaviour and cosmic events (since there has never been shown to have a correlation before, except during solar eclipses).  Check their food or any stressful factors instead before trying to blame the universe.

Chances are they have a visiual cue to the colour of the berries. Its really a co-evolutionary thing. The tree wants to spread its seeds so it signals to the bird with bright red berries for example....come and eat me. Also many birds have very acute vision.....think of vultures flying high above the plains scanning for carrion. Animal senses can be very different from ours.\nCheers.

as a farmer I might be able to put more light on this question. \nit is true that birds do drop seeds, then the trees grow, but most planted fields are bushhogged and plowed so that any new sapling would be destroyed. Some farmers purposely leave a few trees in the fields. if they pasture horses or cattle the trees provide shade. also the tree may provide erosion control if it is on a slope. I personally have trees in my fields to mark sink holes and large rocks that might damage my tractor. \nThere are many reasons that a lone tree would be in a field... perhaps the farmer looked at it and found beauty in it or perhaps his grandmother planted the tree before she died..

You don't need to protect them, don't you see that there are many of them on the streets already. Instead, let it be, it's because of men interfering on nature's business that our system is unbalanced as it is. Quest for thinking: why do you see more pigeons than any other species of bird? Answer: Because pigeons can adapt easily to any environment.

Reminder: 5n Theory, all continents used to be attached to one another- so in theory this is highly possible- if two of every species has moved from place to place. Also remember, animals have a good sense of unusual events happening, like earthquakes and things, so they might have had the sense to know where to go. Then you might ask about the unicorns, but it is said that they were too stubborn to get on the ship... dragons and pegasuses... I have no idea about.

There have been plenty of studies but nobody seems to have a good answer!\n\nI visited a zoo last Sunday (my kids took me, lol) and there were plenty of sparrows there - nesting as well.\n\nhttp://www.birdsofbritain.co.uk/bird-guide/house-sparrow.htm
