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.
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.
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.

Sense its movements through its feet? To find the answer, researchers buried worms in soil in a tray. They covered the soil with a thin but opaque sheet of cardboard, followed by more soil, so the robin couldn't see the worms. Still, the robin found them with ease.
The birds are able to see worms that are close to the surface in their tunnels, but they also can hear them digging and moving about. Most birds, with notable exceptions, have a poor sense of smell.
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!

Robins feed on insects (especially beetles) and worms. You might notice one following you about as your dig up your garden hoping to nab a few worms as you unearth them. Robins can also eat fruit, seeds, suet, crushed peanuts, sunflower hearts and raisins. They particularly enjoy mealworms.
“Speaking of food,” she continued, “have you ever seen robins running and stopping, and running and stopping across your lawn?” Answering in the affirmative, I asked her why robins did this. “Well,” she said, “when the weather warms, we robins like to forage on the ground for worms and such.”
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.
As the birds walk around, their stomping shakes up the earthworms underground and makes them move around, making it easy for the birds to find them. Girl robins eat more worms than boy robins, and warblers like fuzzy caterpillars even better.
The researchers say that although the popping sound could just be due to rapid movements in the attack, it could also be a call to other worms of the same species to let them know they are under attack. Regardless, their roar makes these soft-bodied creatures seem awfully tough.
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.
Magpies can hear the sound of grubs and worms under the ground.
When looking for worms, blackbirds rely on keen eyesight and hearing. They are able to spot a worm's tail sticking out of the soil and can even hear worms when they move under the surface. Berries are a key source of winter food for blackbirds.
Robins use their sense of sight to find worms, says robin expert Laura Erickson. When robins tilt their heads, they're actually using one eye to look for worms in their underground tunnels—and the other eye is focused above, so the robin can spot predators, too! Go outside and observe robins in your backyard.
The worms have two types of auditory sensory neurons that are tightly connected to the worms' skin. When sound waves bump into the worms' skin, they vibrate the skin, which in turn may cause the fluid inside the worm to vibrate in the same way that fluid vibrates in a cochlea.
A web site for fans of earthworms tackled the question recently: Yes, it is now accepted that worms feel pain – and that includes when they are cut in half. They do not anticipate pain or feel pain as an emotional response, however. They simply move in response to pain as a reflex response.
Earthworms are safe and fun to touch, as this Discovery Garden visitor proves.
Calls. American Robins often make a mumbled cuck or tuk to communicate with each other or a sharp yeep or peek as an alarm call. They also make a repeated chirr that rises in volume and can sound like a laugh or chuckle.
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!
If you see a bird lying on the ground with its wings spread, you can be pretty sure it's doing something called anting. Some birds just let the ants crawl on them, while other birds pick up ants in their beaks and rub them on their feathers. Scientists aren't sure why birds do this.
The simple answer to this question is YES! Robins can recognise humans. For the most part, robins recognise a human's traits, such as the way they move, walk and even facial features. For the most part, though, robins closely follow your schedule and movements, especially when food is involved.
The well-known phrase, 'When robins appear, loved ones are near', alludes to the belief that the robin is a messenger. When robins are seen, some people take comfort that loved ones are at peace, and many believe that their lost loved ones are visiting them.
