is it true that predatory birds do not hunt near their nest sight?

This statement seems to agree with that:\n\n"Raptors may also permit small birds such as House Sparrows and kingbirds to build their tiny nests in the raptors' ample platforms or to be close neighbors. These small birds sound the alarm when an intruder approaches, but are not threatened by their predatory "hosts," which ordinarily do not hunt near their own nests."\n\nAs does this:\n\n"Woods where Cooper's hawks nest may remain heavily populated with songbirds, as these hawks hunt away from their nest area."

Cardinals do not migrate, but individuals may wander over a widespread area.

Raptors (diurnal birds of prey) have a region of their retina that provides a higher level of detail, virtually a zoom-in section.  They use this in spotting terrestrial prey from aloft.

I believe such an animal the term low-light vision is used. Such as an owl. Most birds are sight-driven and have excellent vision. The owl has excellent day vision and excellent night vision because its pupils can dialte to allow moonlight or starlight sufficient lighting to see by. This is not to be confused with infravision which is totally different than low-light vision. That would allow the heat an animal gives off to be seen in the dark.

The four species of the genus xenops protect themselves in the same way that most small songbirds around the world - they fly away.  Once the bird is aloft, it is beyond the reach of most predators.  And if you have ever tried to watch xenops in the wild, you know how fast and skittish they are.  Additionally, the drab female xenops look much like the tree bark and rain forest floor where they are often found, making her that much harder to spot.  Xenops nests are secreted in holes in tall rain forest trees, outside the reach of most predators.

I am not certain what you mean, but if you are asking about their breeding and nesting details, Here goes:\n\nWhoopers usually build a nest in marshes or shallow ponds, in about 25 cm of water (the flightless chicks can swim to escape predators) and most often in relatively dense stands of bulrush. \n\nA pair usually has two eggs. Both eggs generally hatch, but if both eggs are left in the nest, usually only one chick survives. The reason for this may be related to a food shortage, particularly when wet areas begin to dry out and terrestrial predators, such as the gray wolf, are able to penetrate the cranes' nesting marshes.\n\nThe incubation period is 29� 30 days, and both parents share the task of incubating the eggs in the nest. Few eggs are lost to predators thanks, in part, to the vigil of the adult birds. The reddish orange young hatch during the last week in May or the first week in June. From then on, the parents are kept busy feeding their chicks. During the summer, the cranes rarely fly. Some birds may be incapable of flight during short periods due to the molt of major wing feathers.\n\nFamily groups frequent the shallows of small ponds and marshes, where the adults perhaps find larval forms of insects such as dragonflies, damselflies, and mayflies, and also snails, small clams, water beetles, leeches, frogs, and small fish to feed their young. When the parent birds kill larger prey, such as snakes, mice, small birds, ducklings, and even birds up to the size of half-grown bitterns, they share the spoils of these hunts with their young.\n\nBy the end of September or early October the young birds are ready to try their wings on the 4000 km migration to the Texas winter range. On the way south, the birds spend one to five weeks feeding in their staging (stopover) areas in Saskatchewan. In these areas, undisturbed whoopers may spend the entire one- to five-week staging period on the same quarter or half-section of land. Here the birds fatten up on waste barley and wheat in stubble fields, and roost during the night in nearby wetlands.

They don't. Simple answer. Some might, but most don't - otherwise how would the population ever increase? If there are only ever a set number of nests then all the newborn swallows from last year will always need to find new nests... taking over nests from last year too if they come back early enough / making new ones themselves.

Most birds who nest in trees weave their nests in order that it stay  together.  If birds just piled stuff up it would blow  away in a strong  wind.  But there are a number of species of birds who weave elaborate hanging woven nests.  The generic name for these is "weaver birds".  They live in large colonies, weaving their nests very close together  in the same tree.  There are also a  number of species of  "Bower birds", who create elaborate bowers, part of which is woven into an arch.  These bowers are not actually nests, however, but male displays aimed at attracting females.

i watched a tv program on this about birds that swarm and its all to do with a few factors ie all the birds are equal distance apart for flying purposes . no bird wants to be on the outside of the swarm or flock due to predator that target such swarms "falcons". so if you can visualise a bird has to have a zone around it to fly and it don't want to be on the edge.when the bird  near it moves to the centre of the swarm to stop being on the edge.the new bird that's exposed whether it be from the side above or below that bird will then move to gain cover in the swarm.hence the shapes you get and the sudden change in direction of the swarm you see in the sky.there is a a computer graphic program that runs this formula but i don't were to tell you to go for this.

I've seen baby squirrels on the ground-their parents protect them so maybe you're not being still enough\nA hunter I know was in camo in a tree being real still and one ran up his arm!\nKeep looking

Tigers usually hunt in the tall grass (the grass is USUALLY dry, brown yellow). The stripes match the up-and-down pattern of the grass, convenient for catching prey in the wild. They are able to stalk silently and be unseen until - ROAR... the antelope meets it's maker. :'( a bit sad...

I get deer in my back yard from time to time. They eat the bark off whatever trees I try to plant.\n\n I have a hedgehog and a family of ringneck doves.  A magpie, two voles have a nest under my patio, a wren has a nest under the eave of my front porch.\n\n An owl did live in my back yard but the tree was 300 years old and fell down a few years ago. The owl moved to the woods behind my house. I still hear him hunting at night.\n\nLast spring, I saw a wild boar at dawn but that was only once.\n\nFunny thing is, I live about 20 minutes from the middle of downtown (city of 500,000). Wild, huh?

Birds don't produce milk, so they can't digest it.  Parent birds regurgitate food for their babies, so the babies get a partially digested paste of whatever the parents have been eating.  This varies according to what kind of bird it is.  There is a good commercially produced hand-feeding formula for seed-eating birds, but it won't provide proper nutrition for birds that eat anything else, and improper feeding can kill a bird just as quickly as not feeding it at all.\nThe best thing to do with any baby wild animal you find is to leave it where it is.  The parents will usually come back for it.  If they don't, find a wildlife rehabilitation center in your area and take it to them as soon as possible, being sure to keep it warm on the way.\nLots of well-meaning people pick up babies they think are orphaned or abandoned, and many of those babies don't survive even the best attempts to raise them.  Please keep that in mind before you pick up any animal you find!

I believe they're cavity nesters. In other words, they would nest in holes in trees in the wild, so it wouldn't look like much from the ground. They are also a common users of manmade bird houses.

No, birds are stimulated to sing based upon what they hear, not what they see- the bird song is made specifically for this, so that potential mates and/or potential intruders on territory are aware of each other even though they are not in sight.

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.

Many birds use the nests abandoned by others. The snug, safe cavities hammered in a tree by woodpeckers may be used by house wrens, tree swallows, screech owls, or bluebirds. The solitary sandpiper will raise its family in the old nest of a thrush or blackbird. \n\nSo I say keep the nest up there!
