Introduction to the Eurasian Collared Dove

The Eurasian Collared Dove is now a common bird in many places around the world. It has traveled from its original home to new lands, showing how birds migrate and adapt. This bird’s story is a great example of how species can spread and thrive in new areas.

Origin and Spread

Originally from Turkey and the Balkans, the Eurasian Collared Dove started moving west in the early 1900s. By the 1950s, it had reached Western Europe, including the UK. Then, it moved even further, reaching the Bahamas in the 1970s.

By the 1980s, it had spread to Florida and quickly covered most of North America. This shows how fast these birds can adapt and spread out.

Physical Characteristics

Eurasian Collared Doves are bigger than Mourning Doves but smaller than Rock Pigeons. They have a light brown to gray-buff color and broad white patches on their tail. A unique black crescent mark is on their neck, giving them their name.

When they fly, you can see their wide, slightly rounded wings with darker tips.

Scientific Classification

The name Streptopelia decaocto for this species tells us a lot about it. “Streptopelia” means “collar” and “dove” in Greek. “Decaocto” comes from a myth about how it was made.

Habitat Preferences and Adaptation

Eurasian collared dove habitat adaptation

Eurasian collared doves are amazing at adapting to different environments. They live in both cities and the countryside. These birds help make cities more diverse by fitting right into our changed landscapes. They are now common visitors in many backyards.

They like open areas with a few trees, so gardens and parks are perfect for them. To draw these doves in, plant tall trees and shrubs. They need these for shelter and places to nest. A study by Havlíček et al. (2021) showed how important green spaces are for these birds in cities.

These doves have special ways of finding food. They mostly eat seeds and prefer to forage on the ground. To help them, put out a feeder that’s easy for them to reach. Use a mix of millet, sunflower seeds, and cracked corn. This is backed by research by Poling and Hayslette (2006) on what these birds eat.

El-Mansi et al. (2021) studied the Eurasian collared doves’ digestive system. They found that these birds can live in many places because of their unique body traits. This helps them move into new areas and grow their numbers.

Breeding Behavior and Nesting Habits

Eurasian Collared Doves have interesting nesting habits that help them spread across North America. They live in many places, even cities, which has made their numbers grow fast.

Mating Patterns

These doves are monogamous, staying with one partner for life. They start breeding in March, but can do so all year in mild places. This has led to a big increase in their numbers, especially since they arrived in Florida in the 1980s.

Nest Construction

Building nests is simple for these doves. They use twigs, debris, and dry grass. Most nests have more twigs, debris, and grass. They pick trees, shrubs, or even buildings like gutters for their nests, showing they can live in cities too.

Breeding Season and Clutch Size

Eurasian Collared Doves breed a lot. Females lay two eggs at a time and can have up to 6 broods a year. They usually lay 1 to 2 eggs, with an average of 1.7 per nest. Both parents take turns incubating the eggs for about 14.5 days. The chicks leave the nest after 17 days.

This breeding helps their numbers grow fast. There are now about 85 million of them worldwide. For more info on parrot breeding, check out the Vernal Hanging Parrot.

Diet and Feeding Habits

Eurasian Collared Dove feeding habits

Eurasian Collared Doves eat a wide variety of foods, showing how adaptable they are. They love seeds and grains, which brings them to bird feeders in gardens and parks. They’re especially fond of sunflower hearts and seed mixes.

But they’re not just seed eaters. They also enjoy berries, small insects, and worms. This variety in their diet helps them thrive in different places.

Some farmers see these doves as pests because they eat new crops. Yet, they play a key role in spreading seeds and controlling pests. Knowing how they eat helps with bird feeding and farm management.
