I have noticed that birds, within a few pecks into the ground, can bring up a worm. I cannot believe this is because there are that many worms in the ground such that it is a chance occurrence. So how do they know where the worms are?

Birds feed on many foods but most birds like to feed on worms. Interestingly, different birds are equipped with different features to locate worms. An ornithologist or bird specialist at Cornell University in Ithaca, New York said some birds seek out worms by touch, some by sight and some by smell. For example, shore birds like sandpipers have very sensitive tips on their bills. They can often feel worms that they may not see. Kiwis actually have nostrils at the tips of their bills and a very good sense of smell allowing them to find earthworms and other foods. But what about the backyard favorite, the robin? It appears, as the song says, to be "bobbin' along". When the robin is searching through the grass to find dinner, all studies suggest they are doing it entirely visually, not by hearing or smell. When the robins run along the grass cocking their heads, it appears that they are listening but all of the data suggest they are just looking. What are they looking for since many of the worms are below the surface of the lawn? They look for the castings or pellets of mud on the soil surface indicating the entrance to a worm hole. In the winter it may be more difficult for the birds to find sufficient food so bird seed or bread crumbs are a welcome treat. And don't forget that the birds need water, too--in summer and in winter.

fly's (throw up) on the food they are about to eat. they secrete stomach fluids onto their food so it starts digesting it and then they slurp the digested food and stomach fluids up! yummy.

Yes indeed, I agree with you that it would be easier for them to chew worms if they have teeth. However teeth are heavy and would make it very difficult for birds to fly.  This is especially important for birds of prey who must fly swiftly to catch their food. Due to this "anatomical structural design"  birds have light  beak which is good for giving food a good mashing. Birds "chew" their food inside a part of the stomach called the gizzard.  The gizzard has strong muscles which grind the food against a rough inner surface to break it down.♥

They dont really eat anything as such. They have sensors sort of thing between the trap. When any foreign body, say bug, flies or even ur finger comes in it, it senses it and instantly the trap closes. then the nitrients from the body of the foreign body are extracted and used for the plant's nutrition.

I don't know if there's a proven fact if animals could laugh but I'm sure they could as well as any human beings.\n Just as we could teach our pets certain things, so are wild animals have their own kind of communication on how to survive from predators and who knows one of them might be laughter. Seems like some birds do know how to laugh too.

They must have escaped from someone - they are not native to America.  They may have been adopted by the starlings, so they will probably survive. They don't usually live in such cold climates though. Help them by feeding them through your bird feeder.  Just out of curiosity what colour are they???

I would go knock on somebody's door and offer to clean their house in exchange for food. I would gladly do that for someone in need myself. The important thing is you have to go out and look for it. God feeds the birds, but He doesn't drop the worms in their mouths. Good Luck!

They can go anywhere they won't get wet. This includes places like the bark and leaves of trees, porches, grass, or anywhere else. But I suspect many just die, and it is the babies that live on. Flies don't live very long anyways, and the larva grow up fast. If a generation of flies die, the next will be around in a little bit.

A quick question with a quick answer: They're not blind.\n\nBut if you're still curious if they use it to navigate around... No.\n\nThey use their hypersensitive antennae to navigate, distiguish objects, detect vibrations and find their food.\n\nA cockroach with its antennae cut off will die of starvation.\n\nI do this ALLLLLLLLLLL THE TIME!!!!\n\nAND ITS FEEEEEEEEELLS SO GOOOOOOOOD!!!\n\nYucky creepy bastards!

Crabs... the kind you get down there, are tiny.  Not visible to the eye.  You probably had a bug on you and it scrambled across you nether region.  \n\nIf you had crabs down there you would know it for sure.  You would be itching like a Motherfu**er.

simple animals have this total regeneration ability, even more, if you cut an earth worm to several pieces, each can regenerate to a complete worm.\nthis is very typical of plants.\nmore advanced/complicated animals have a much smaller regenerative ability. something in the genes of the primitive earth worms is lost among the more advanced animals.

Pigs can't fly.\n\nPeople are more concerned about birds that are migratory and can carry the disease form place to place.

Millions of people are infected by the parasites worms worldwide. Parasites can enter our bodies through food, water, mosquito bites, or through the nose and skin. More than 100 types of parasites worms can be living happily in human bodies. Some are big in size that can be seen by eyes, while the others are microscopic in size. Only about 5 percent of these varieties can be tested positively with only 20 percent accuracy. \n\nParasites worms find a perfectly living environment when the bowel becomes ineffective in the elimination of the waste products due to constipation. \n\nParasites may be categorized into four types: Protozoa, Trematoda, Cestoda, and Nematoda. Nematodes include common roundworm, hookworm, whipworm, pinworm, heart worm, etc.

They are social creatures and likely to hang out where everyone else does - like people!  They tend to gather in flocks too.  If it's near intersections my guess would be that's because it's between two clear fly zones, where there are not tall trees or buildings to get in their way as they fly.  They like to stay relatively close to the ground for warmth, water, food, action...and wires are everywhere so they are used to hanging out there.  \n\nAnother thought...People are not going to bother them or threaten them if they are sitting on electrical or telephone wires - those birds who sat there learned that, and the birds who chose the buildings and windowsills didn't fare as well.  The survivors spread the wisdom to their offspring (a Darwinian explanation, but makes sense even if you're not a Darwinian).

http://en.wikipedia.org/wiki/Parelaphostrongylus_tenuis\n\nMorphology\n\nRoundworms are triploblastic protostomes with a complete digestive system. Roundworms have no circulatory or respiratory systems so they use diffusion to breathe and for circulation of substances around their body. They are thin and are round in cross section, though they are actually bilaterally symmetric. Nematodes are one of the simplest animal groups to have a complete digestive system, with a separate orifice for food intake and waste excretion, a pattern followed by all subsequent, more complex animals. The body cavity is a pseudocoel (persistent blastula), which lacks the muscles of coelomate animals used to force food down the digestive tract. Nematodes thus depend on internal/external pressures and body movement to move food through their digestive tracts. The mouth is often surrounded by various flaps or projections used in feeding and sensation. The portion of the body past the anus or cloaca is called the "tail." The epidermis secretes a layered cuticle made of keratin that protects the body from drying out, from digestive juices, or from other harsh environments, as well as in some forms sporting projections such as cilia that aid in locomotion. Although this cuticle allows movement and shape changes via a hydrostatic skeletal system, it is very inelastic so does not allow the volume of the worm to increase. Therefore, as the worm grows, it has to moult and form new cuticles. The cuticles don't allow volume to increase so as to keep hydrostatic pressure inside the organism very high. For this reason, the roundworms do not possess circular muscles (just longitudinal ones) as they're not required. This hydrostatic pressure is the reason the roundworms are round.\nMost free-living nematodes are microscopic, though a few parasitic forms can grow to several meters in length. There are no circular muscles, so the body can only undulate from side to side. Contact with solid objects is necessary for locomotion; its thrashing motions vary from mostly to completely ineffective at swimming.\nRoundworms generally eat bacteria, algae, fungi and protozoans, although some are filter feeders. Excretion is through a separate excretory pore.\nReproduction is usually sexual. Males are usually smaller than females (often very much smaller) and often have a characteristically bent tail for holding the female for copulation. During copulation, one or more chitinized spicules move out of the cloaca and are inserted into genital pore of the female. Amoeboid sperm crawl along the spicule into the female worm.\nEggs may be embryonated or unembryonated when passed by the female, meaning that their fertilized eggs may not yet be developed. In free-living roundworms, the eggs hatch into larva, which eventually grow into adults; in parasitic roundworms, the life cycle is often much more complicated.\nRoundworms have a simple nervous system, with a main nerve cord running along the ventral side. Sensory structures at the anterior end are called amphids, while sensory structures at the posterior end are called phasmids.\n\nhttp://en.wikipedia.org/wiki/Nematode\n\n\nHope that helps!

You should enjoy watching them, they are a sign that nature is recovering in your area. I know of no wives tales or superstitions about hawks (ravens and crows and vultures, that's another story.)\n\nAlso, hawks only eat fresh, so it definately doesn't mean there's road kill around.

They are well known scavengers that we follow the farmers plough to pick off titbits (worms, etc) that are exposed when the soil is tilled. Not to mention, at the landfill sites for household waste.
