While the majority of American Robins migrate to the south each fall, a small number of stragglers usually remain behind and endure the winter. The majority of over-wintering robins are males trying to ensure they have first choice of nesting territories in the spring. Females migrate to areas where food is more abundant to help ensure they are in top condition for the rigors of raising young in the spring. Male robins that migrate usually arrive on the breeding grounds up to two weeks before the females return.
American Robins migrate in flocks primarily during the daylight hours. Robins are attracted to open lawns and gardens with mature shrubbery and trees. While they eat a variety of insects and berries, it has been noted that robins can eat up to 14 feet of earthworms in a day!

This happens most frequently when they were successful raising babies the previous year. A clutch consists of three to five light blue robin blue eggs, and is incubated by the female alone.
The eggs hatch after two weeks and the chicks are bald and have their eyes closed for the first few days after hatching. Baby robins poop in fecal sacks consisting of thick, strong mucus that a parent robin can pick up and dispose of easily, thus keeping the nest clean.
While the chicks are still young, the mother sits on the nest continuously. When they are older, the mother will sit on the nest only at night or during bad weather. The chicks leave the nest after two weeks and even after leaving the nest, the juveniles will follow their parents around and beg for food.
The male and female both are active in protecting and feeding the fledged chicks until they learn to forage on their own. The adult Robin gives alarm calls and dive-bombs predators, including domestic cats, dogs and humans that come near the young birds.
The fledglings are able to fly short distances after leaving the nest. The wings of juvenile birds develop rapidly, and it only takes a couple of weeks for them to become proficient at flying. Only 25 percent of young robins survive.
The longest known lifespan in the wild of an American Robin is 14 years, while the average lifespan is about two years. The Tlingit people of Northwestern North America held the Robin to be a culture-hero to please the people with its song. Breckenridge resident Dr. For example, they can use tools, solve problems, and recognize human faces.
It seems that crows even do things just for fun! American Crows have a large vocabulary. Listen for any number of caws, rattles, cackles, and clicks. Sparrows can be incredibly difficult to identify, due to how many types of sparrows there are and the fact they look very similar. But luckily, Song Sparrows are one of the easier sparrow species to determine correctly.
These birds are common in Colorado , especially in wet, shrubby, and open areas. Unlike other birds that nest in trees, Song Sparrows primarily nest in weeds and grasses. Many times you will find them nesting directly on the ground. My favorite feature of Song Sparrows is their beautiful songs that can be heard across the continent.
The typical one, which you can listen to below, consists of three short notes followed by a pretty trill. The song varies depending on location and the individual bird. White-breasted Nuthatches are compact birds with no neck, a short tail, and a long pointy bill.
Color-wise, they have distinctive white cheeks and chest, along with a blue-gray back. Look for these birds in Colorado in deciduous forests. But they adapt well to the presence of humans and are often seen at parks, cemeteries, and wooded backyards visiting bird feeders. To attract nuthatches, use sunflower seeds, peanuts, suet, safflower seeds, and mealworms. These birds are incredibly vocal AND make distinctive noises that are relatively easy to identify!
This loud and distinctive noise is often repeated several times in a row. Press PLAY to listen below. During the breeding season, these birds are almost exclusively found in marshes and other wet areas. Females build nests in between dense grass-like vegetation, such as cattails, sedges, and bulrushes.
Males aggressively defend the nest against intruders, and I have even been attacked by Red-winged Blackbirds while walking near the swamp in my backyard! If you visit a wetland or marsh in spring, you are almost guaranteed to hear males singing and displaying, trying to attract a mate. The rest is history as starlings easily conquered the continent, along the way out-competing many of our beautiful native birds.
Their ability to adapt to human development and eat almost anything is uncanny to almost no other species. When starlings visit in small numbers, they are fun to watch and have beautiful plumage.
Unfortunately, these aggressive birds can ruin a party quickly when they visit in massive flocks, chasing away all of the other birds while eating your expensive bird food. To keep these blackbirds away from your bird feeders, you will need to take extreme action and implement some proven strategies.
Even though they almost never visit bird feeders, they are often seen zipping through backyards while hunting insects. A great way to draw these wrens to your yard is to create brush piles, which offer cover for them and places for insects to gather. Appearance-wise, House Wrens are small, brown birds.
They have a short tail, thin bill, and dark barring on their wings and tail. Both males and females look the same. House Wrens are commonly encountered by people when their nests are found in odd places.
For example, when I was a kid, I remember we found a nest in a clothespin bag hanging outside. Before my mom could access her clothespins, she had to wait until the wrens had raised their young and abandoned the twig nest! Other weird spots for nests include boots, cans, or boxes. The best way to describe it is a beautiful, energetic flutelike melody, consisting of very rapid squeaky chatters and rattles.
Look for them perched high up in trees or on a telephone wire near your home.
