“Migration has begun”: where to see bald eagles returning in large numbers to Colorado



According to Colorado Parks and Wildlife, the bald eagle’s annual migration to Colorado has begun.

Every year, from November to March, migratory bald eagles return in large numbers to Colorado from the north, and more than 1,000 eagles are expected to cross the state this winter. Barr Lake State Park reports that 35 birds were spotted by volunteers on Wednesday, and more eagles are expected to pour into the state in the days and weeks to come.

When it comes to eagles, they are a bit unique in terms of migration. For starters, not all of them migrate.

Colorado is home to around 200 breeding pairs and these tend to stay in the state year round. Their migratory counterparts will pass, but even then they are not as consistent as other bird species.

Several factors play a role in when and where an eagle will migrate, including the age of the bird, food availability, and where the bird lives. Whether or not a bird is a breeder is also a factor, as these birds are likely to remain in their nesting area throughout the year.

According to the Bird Conservancy of the Rockies, one of the reasons the northern and eastern eagles choose Colorado is the subsequent freezing of the state’s water bodies. This means that one of the eagles’ main food sources – fish – can be caught later in the year.

If you’re looking to spot a bald eagle this season, here are twelve places you have a good chance:

Four tips for spotting bald eagles:

1. Look near water sources, including rivers, lakes and reservoirs. This is where bald eagles tend to find their food, so they rarely travel far from these places.

2. Use binoculars. This will greatly improve your chances of having a good view of a bird.

3. Go scouting in cold weather. Eagles tend to perch longer in colder weather, making them more predictable and easier to see.

4. Dawn and dusk are good times to spot perched eagles. Eagles tend to congregate in one place when they go out for the night. Look in the thickets of trees by the lake.
