Chestnut Backed Chickadee

Chestnut Backed Chickadee, Vancouver Island, BC

The Chestnut Backed Chickadee is a frequent visitor to our feeders on Vancouver Island and is a joy to interact with. They sometimes look comical when they land on a branch close to you and turn their heads almost upside down all the while calling with the cheep cheep cheep call.

They are very friendly and quite beautiful when observed up close. I have had them land on my shoulders as l fill their feeders, chirping at me loudly as if to tell me to hurry it up. They are a small energetic bird with a chestnut-brown back, rump, and flanks. They have white cheeks, a black throat, and gray wings and tails. Their chests and bellies are all white. They have short bills and their average length is 10 cm. Male, female, and juvenile chestnut-backed chickadees all share the same plumage.

The Chestnut Backed Chickadee build their nests in woodpecker holes or excavate their own cavities in soft rotten wood. They are also known to nest in man-made nest boxes. The nests are built using moss, lichen, fine grass, feathers, and plant fiber, and are lined using soft hair and fur. The nests are usually placed low and do not exceed 2.5 meters above the ground.

The female chickadee lays 5 to 7 eggs usually white eggs. Some eggs although white, are speckled. Both male and female chickadees tend to their young while nesting.

Little is known about the mating habits of these chickadees. So far there is no information available regarding their mating behavior or pattern for pair formation. What is known is that chestnut-backed chickadees become territorial during the breeding season but otherwise freely join mixed-species flocks, especially in winter. Breeding season starts around mid-March to early April.

The Chestnut Backed Chickadee get their food by foraging. They hop along tree branches and pick the surfaces and probe crevices in order to find food. They are often seen hanging upside down from tree branches in order to get to the food found on the branches’ underside. They like to forage in conifers and even eat conifer seeds. The main diet of chestnut-backed chickadees is composed mainly of insects and spiders. They also seem to like the suet and birdseed found in bird feeders. They store food in the fall, which they retrieve and use during winter. This spring, l observed them hanging upside down on salmonberry flowers, licking up the nectar.

lthough they are non-migratory they sometimes fly short distances in winter when their food supply gets low. They usually move to lower elevations in the same area when winter starts and move back up to higher elevations in late summer.

Chestnut Backed Chickadees use lots of fur and hair to make their nests. Their nests are actually 50% fur and hair. The most common hair they use comes from deer, rabbits, and coyotes. The adult chickadees also make a layer of fur about a centimeter thick which is used to cover the eggs on the nest whenever they leave the nest. When we brush our dogs in the spring, we place the hair in areas where chickadees and other birds can gather it to use for nesting material.

  1. Hi Bud
    We have these sweet birds at our feeders in Maple Bay Properties in Duncan. It is fun to watch them on our pear tree outside the window. They do hang upside down. I wonder what they are eating on those branches.
    I really am happy to have found your site. This is a gift to our family as we so love learning about birds outside our windows, on our decks and in the trees.
    when we have supper, we call it Dinner and a Movie…and say that all of us, birds and us humans, are having a great evening as we watch them through our sliding door and they maybe are observing us too.
    Thank you to you and your boys for providing such excellent information.

  2. Love your website. It’s the most complete and informative site I’ve found. I’ve been able to identify ever bird I’ve been watching and love all the details you provide about each one.
    Thanks so much.
    Would love to have all this info in a book.
