How do worm-eating birds identify a specific piece of earth containing worms?

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.

The earthworm has a body cavity through which the intestine passes with a front part that is modified to form special structures. The muscular throat sucks food into the food storage organ and it has a gizzard (a muscular organ in which food is ground into smaller pieces) that will grind food. They have an intestine (a region where chemical digestion and absorption occur). The intestine is tube-shaped and runs the entire length of the worm. It has a very tiny brain that is connected to a nerve cord that lies under the intestine. This comprises the nervous system of the earthworm.

Earthworms do lay eggs.

If by "red worms" you mean earthworms of the species Eisenia foetida (commonly used for composting), they mostly eat any plant or animal particulate matter that is small enough to enter their mouths; other species (including another common earthworm of genus Lumbricus) can use their sucker-like mouth to ingest relatively large pieces of food. They also ingest live microorganisms along with the detritus. \nEarthworms are part of the soil mesofauna, and usually they don't feed on whole plant parts (such as leaves) but rather on small pieces of particulate matter that have already been generated by other animals of the macro- and mesofauna, especially plant residues (coffee grounds and tea leaves included). They ingest these along with soil inorganic particles (that's why they are important for mixing and carrying organic matter into deeper soil layers).

That is a good question. Some birds and some insects use the magnetic field of the earth to give them clues for navigation, along with landmarks, and polarization of light etc. My guess is that at first they might be a little confused, but they use multiple clues, so they would soon adjust and learn the new pattern. \n\nAfter all, it flips fairly often on earth's time scale.  Apparently on average it flips every 300,000 years, and  the last flip was 780,000 years ago, so we are a bit overdue at the moment. Obviously, the birds have survived through lots of flips, and movements of the earth and landmarks etc. So they will probably survive the next flip too, but not necessarily without some confusion.

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.

The excreta and saliva  of birds contain the virus.They get dried up on earth.Contamination of these with food is one way.Birds are not boiled but only fried.This does not destroy virus.Eating ill cooked birds is another way.

There are many types of worms i think it depends on the type...if you say a ringworm well microscopically its pesty carnivore coz it eats you up...but if you say an earthworm well its an omnivore coz it lives down on muddy earth deep in the soil...ok human friend but for more info browse the web human friend!!!oh! more info some poeple eat worms! YUCK!

Greetings,\n\nCruithne discovered in 1986.\n\nWe currently have a couple of asteriod size objects oribiting the earth, if that is what you are referring to (Reference the first website listed as sources.)\n\nWe also have any number of Near Earth Objects captured by Earth's gravity, the second link posted.\n\n-matt

No.  Worms do not breath as we do.  They are essentially just one long dirt processing plant.  All gut.  If I remember my High School biology correctly, worms absorb oxygen through their skin, thus do not have breath or lungs.  \n\nPS:  You can cut a worm in half at the smooth section in the center, and it will crawl of and remain alive as two separate worms!!  Cool, huh?\n\nPSS: anojetak ... to funny!!

I can't find anything on that - looks like you are going to have to do an experiment.  You can find earthworms at any bait store, colored light bulbs at the nearest Wal Mart.  have fun!

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.♥

It's impossible to identify the worm from that description.  There are a number of options.\n\nHowever, my best guess is that it is a horsehair worm.  Horsehair worms are rather fascinating creatures, possibly responsible for inspiring the film "Alien".  Adult worms live in water where they lay their eggs.  The eggs hatch into larvae, who make their way to an appropriate place to be eaten!  Once an insect (usually a grasshopper or a relative, such as cockroaches) eats them, they crawl out of it's digestive system and live in it's abdomen, growing every larger.  When they become adults, they secrete a chemical, causing the insect to get very thirsty.  It rushes to the nearest body of water, where the horsehair worm tears it's way out of the insects stomach and into the water, where it looks for another horsehair worm so it can start the whole process over again.

Scientists don't have all the answers, but current theory says migrating birds have a "map and compass" system. The map gives them location and the compass provides direction. They may use observation and memory, and hard-wired (instinctual) information for the map. There are believed to be 5 basic navigation mechanisms: steering by the sun; steering by stars; biological-magnetic map (for location; is sensitive to magnetic disturbances); magnetic map (for direction); and odor map (for short distances). See the ref. for details.

Birds hear a lot better than we do, and worms moving around in soil make noise that is distinctive. OR, maybe they have Xray vision! :-)

There is lots of factors limiting where worms can live.  For example: food availability, water availability, oxygen availability, compaction, temperature (frozen soil or boiling hot soil), etc

probably like any sea bird.. I know I live on the coast of an ocean and the birds poo is usually greenish/grey/with specks of white in it.. I guess depending on the fish or junk they ate prior to that..
