Robins hunt earthworms by alternating between standing motionless and erect for brief periods and making short runs or hops. Once an earthworm is detected, the robin moves closer and crouches, cocks its head presumably to look and/or listen, and then thrusts the bill into the soil to catch the worm.
Some of that foraging can also be done by sight. Worms, for instance, may leave a small mound (called a cast) on the surface and, to the experienced bird, this indicates that a worm is just below. Magpies can also go a huge step further. They can identify big scarab larvae underground without any visual help at all.
Vision: Birds, including robins, find worms mostly through sight. Birds have exceptional vision, and their keen eyes can spot the tiny end of a worm as it pokes out of the soil. They can also see small changes in soil and grass as worms move about just below the surface, movements that indicate where a worm is located.
But just based on hearing, robins “found the worms with no problem,” says Montgomerie. While visual cues remained important, the birds had significantly less success if they could not use their hearing, according to a report by the scientists in the journal Animal Behavior.

As worms live under the surface of the soil, birds cannot rely on vision alone to find them. They can feel vibrations from worms moving under the soil and also use their acute sense of hearing.
In addition, a bird's feet are highly sensitive and they can feel the vibrations underfoot as a worm tunnels along through the soil. Luckily for birds, when it rains, the worms will often make their way to the surface and this is then an easy time for birds to grab them for a nutritious snack.
So does the early bird really get the worm? The answer is yes, but the night owl gets his as well.
1. Why is Worm scared of the bird? Ans. The Worm was scared of the bird because the bird wanted to eat the worm.
Roundworm eggs are passed out through the feces of infected birds, where they can infect healthy birds. Sometimes, an intermediate host will ingest the eggs and give them a host within which they can evolve into larvae. These hosts are then eaten by a healthy bird, causing a new infestation.
People can also become infected by mouth-to-beak contact (kissing) with birds or by handling the feathers or tissues of infected birds. Case reports suggest transmission may occur from contact with infected aborted material, abnormal equine placentas or symptomatic foals.
While they eat a variety of insects and berries, it has been noted that robins can eat up to 14' of earthworms in a day!
Expect to go through about 100 mealworms per day once birds know where to find them. It's also important to note that mealworms do not provide complete nutrition and should only be used as a supplemental food source, offered on a limited basis. Overfeeding can cause health issues for adults and young!
Dr. Heppner wondered if robins could feel the vibrations worms make and sense them that way. He drilled worm-like holes in the ground and placed dead worms in them. The robins peeked in the holes, found the dead worms, and ate them readily!
Thanks to special molecules in their retinas, birds like the European robins can literally see magnetic fields. The fields appear as patterns of light and shade, or even colour, superimposed onto what they normally see.
Researchers have found that they're most numerous in the crowns of grass clumps—the junction where stems and roots meet. They're shaded there and hidden from birds while they feed on decaying leaves and roots. The grass also offers some protection from high temperatures.
The simple answer is: birds crave protein, but birds eat worms for a variety of other reasons as well. Worms are readily available in nature for birds to feed on and worms are quite easy to catch.”
By five days of age, the nestlings get earthworms that parents break into small mouthfuls. The babies eat more each day. Soon parents give them whole worms and large insects. Each young robin may eat 14 feet of earthworms in a two-week nest life—and worms are not even their main food!
Robins do not eat birdseed, so they are unlikely to be interested in your feeders. They also prefer to forage for their food on the ground, in open areas. You can scatter the mealworms, berries, or chopped fruit around the base of your bird feeder.
Robins are considered to be omnivorous, or an animal that preys upon both plants and other animals. Depending on the season, they typically forage for berries, fruits, seeds, and worms. They rely on their eyesight to find such meals, making them a candidate for diurnal habits where they choose to forage in the daytime.
How smart are robins? A. Robins are not quick to learn new things as blue jays, and do not have as good reasoning power as jays. But they are adaptable, and can quickly figure out how to find food and shelter in a new area where they've never been before.

So if not earthworms, what were robins feeding their chicks before Europeans arrived? Well, probably some of the more than a hundred kinds of insects and other invertebrates, as well as berries, that robins are known to eat. Robins prefer to forage in short grass to avoid potential predators.
Robins, one of the most common birds in North America, are known for hosting and dispersing the pathogens that cause diseases like West Nile Virus and Lyme disease in humans.
Birds kept inside with out access to other birds only need to be wormed yearly as there is little chance of infestation. Outside birds should be wormed more frequently, we recommend 3 monthly worming treatments. You might be wondering how your bird may contract internal parasites.
