Kinds of Wrens in Colorado

 

Wrens are incredible birds and they inhabit many different habitats. Even though they are small, wrens are incredibly bold and don’t back down to other species that are much larger than them.

 

If you encounter one, you can expect to hear loud and complex songs. Once you know what to listen for, it’s easy to identify these birds before ever seeing them! And don’t worry, I have included a sample of the calls and sounds for each species below.

 

Below are the 6 types of wrens that live in Colorado!

Make sure to pay attention to the range maps to see which wrens live near you!

Wrens That Live in Colorado (6)

 


#1. House Wren

Common Colorado Wrens

 

The House Wren is common in Colorado. 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.

To attract House Wrens to your backyard, try hanging a nest box, as these birds will readily use them to raise their young. Please pay attention to the entrance hole’s diameter and try not to make it any larger than 1 inch in diameter. By keeping the hole small, other birds can’t get inside to disturb the wren’s nest and babies. Interestingly, House Wrens are one of the only birds that will use a nest box hanging freely and not permanently attached to a tree or post.

 

House Wrens fight incredibly hard for the nest cavities they want. It’s common for them to peck at much larger birds. And if they really want a particular nesting location, they are even known to drag eggs or babies out so that they can move in.

One of the best ways to locate a House Wren is to listen for their distinctive song. The best way to describe it is a beautiful, energetic flutelike melody, consisting of very rapid squeaky chatters and rattles.

 

Lastly, make sure to read this interesting fact!

 

One problem that House Wrens have is that their nesting cavities can become infested with mites and other parasites, which can harm wren hatchlings. To combat this problem, spider egg sacs are brought into the nest by the parents. Once the baby spiders hatch, they feast on the parasites located in the nests, helping save the baby birds.

 


#2. Marsh Wren

 

Even though Marsh Wrens are common in Colorado, they are not seen often by people. These birds live secret lives under cover of reeds in hard to reach places in marshes and swamps (as the name suggests).

 

Marsh Wrens have a round body with a short tail that is often pointing upwards. Look for a small bird that is rusty brown with black and white streaks down its back and a pale eyebrow. They are often seen clinging to reeds, with each foot grasping on to a different stalk!

Even though Marsh Wrens are tiny, they are incredibly fierce, aggressive, and active. Males typically mate with more than one female and build multiple nests for each female. They are even known to pierce eggs and kill nestlings of both Marsh Wrens and other birds.

These birds are hard to spot in the dense reeds in the habitats in which they live. You probably will have much better luck listening for them. Their songs typically consist of several introductory notes, then a trill of repeated syllables, and then a few concluding notes. The whole series of gurgling and buzzy trills only lasts a second or two, but they can repeat this and carry on for a LONG time.

 

Marsh Wrens are most vocal in the morning and just before sunset, so make sure to head out at these times if you want the best chance of observing one. Also, I have had good luck seeing these birds at parks or wildlife refuges that have an elevated boardwalk through the marsh, which helps greatly with visibility!

 


#3. Carolina Wren

 

This wren species is a colorful reddish-brown with a distinct white throat and eye line. The edges of their wings and tails are darkly barred, and the bill is long and thin. Both males and females appear similar.

Even though Carolina Wrens are common in Colorado, these secretive birds can be hard to see. Look for them in shrubby and bushy areas that provide lots of hiding places.

 

One of the BEST ways to observe Carolina Wrens is by attracting them to your feeders.

Carolina Wrens are the most common wren that visits feeding stations. Look for these birds eating at your feeders in the cold, winter months. I see them feasting on suet the most, but they also eat peanuts, shelled sunflower seeds, and mealworms. Carolina Wrens rarely visit bird feeders during the summer since there are plenty of insects around for them to eat.

 

Carolina Wrens are often heard before being seen!

Their song, which is only sung by males, is usually three-parted and sounds like they are saying “tea-kettle tea-kettle tea-kettle. These birds are impressive singers, and individuals can make many variations of this song, so you never know exactly what you will hear.

 

Carolina Wrens are incredibly dedicated partners. Once a male and female find one another, the bond is typically for life. The pair will stay with each other in their territory year-round and even forage and move around together.

 


#4. Bewick’s Wren

 

Bewick’s Wrens are most often found in dry brushy or scrubby habitats within their range. The best way to identify them is to look for their white eyebrow and dark barring on the tail. As for their personality, these wrens are noisy and extremely active. It’s common to see them flicking their long tail sideways as they hop from branch to branch.

Bewick’s Wren populations have declined through the years, and one of the main reasons is increased numbers of House Wrens. Both of these birds are drawn to the same nest sites. Unfortunately, when competition arises, it’s the House Wren that typically wins, as they are known to destroy nests and eggs.

These wrens, like most species, are extremely vocal. The song that male Bewick’s Wrens sing varies from individual to individual and from geographic area to geographic area. The most common song you will hear has a pattern of a few introductory notes and ends with a high trill.

 

It’s possible to get them to visit your bird feeders.

If one of these wrens does show up, it will be in winter when insects are not around. The most common food you will see them eating is suet, but shelled sunflower seeds, peanuts, and mealworms are also consumed.

 

Lastly, if you have a suitable backyard habitat, you should try putting up a nest box. You may be able to attract a mating pair of Bewick’s Wrens to raise their young! The best entrance hole diameter to use for these birds is 1-1/8 inches.

 


#5. Rock Wren

 

Rock Wrens are pale brown birds that have a long tail and thin bill. If you look closely, you can small white speckles on their back and wings. Males and females look similar. Behavior-wise, it’s common to see them quickly bobbing up and down.

These migratory wrens are found in rocky, arid areas of Colorado.

 

Incredibly, Rock Wrens are not known to drink water. Instead, they get all of their moisture from their food, which consists of insects and spiders. They mostly hunt on the ground, probing around and under objects for prey with their thin bill.

Rock Wrens are prolific singers! They have a large repertoire of songs, which can consist of 100 or more tunes! Interestingly, they can learn new sounds from other individuals. Listen for a mixture of buzzing trills and other musical phrases. When they are not singing, you may hear their common call, which sounds like “tic-keer.”

 


#6. Canyon Wren

 

Canyon Wrens are rusty brown birds with black barring that have a long tail and bill. To confirm their presence, look for their bright white throat and upper chest.

These wrens are common in Colorado in dry, rocky areas. Look for them in places such as canyons, cliffs, boulder piles, and any rocky outcrop. These birds are perfectly adapted for these habitats, and they even have a slightly flattened skull, which helps them probe inside crevices as they look for food.

 

Canyon Wrens are at home in places without water because these birds don’t need to drink! They get all their moisture from the insects they eat. Even when they are near a water source, they are not seen drinking.

These wrens have a lovely song, often described as a series of descending, liquidy notes. These distinctive sounds are often heard echoing through the canyon walls in which they live!
