Black-capped Chickadees- The Cheeseburger Birds

Black-capped Chickadees (Poecile atricapillus) are the most easily recognizable birds we have here in The Land Between (beyond, perhaps, BlueJays), and we think you might agree they are the “cutest” birds here. They are curious, energetic, and downright acrobatic!

Earning their names from both the black “cap” on their heads, and their chicka-dee-dee-dee call, Black-capped chickadees are among the most common and wide-spread bird species in Canada. Their range spans every province and territory except Nunavut, and includes the majority of the northern United States and Alaska.

Black-capped Chickadees live in a wide range of habitats from forests to suburban backyards, essentially anywhere there are trees or woody shrubs and a source of food. Black-capped Chickadees are among the easiest birds to attract to a feeder, eating sunflower seeds, peanuts, suet, and other offerings. When foraging for their own food, they will eat various insects, seeds and berries.

Black-capped Chickadees nest in cavities in dead standing trees or rotting logs. They often excavate and expand existing natural cavities, or take over old woodpecker cavities. They will also use nest boxes when they are provided. Female Black-capped Chickadees ensure the nest is nice and comfy for their offspring by creating a bed of moss, animal fur, or other soft fibers. Females lay 1 egg a day, laying 6-8 eggs, and incubate them for 12-13 days.

To add to their already well deserved appeal, here are 7 additional facts you may not know about Black-capped Chickadees:

1. They Have AMAZING Memories

Black-capped Chickadees will often hide or cache their food to consume at a later date. According to researchers, these birds can remember thousands of food hiding places and can maintain this level of recall for over 28 days! What’s more, it has been discovered that these birds have the ability to discard old neurons in their brains and replace them with new ones, therefore, allowing them to create space for additional important information as they age.

2. They Have a Very Rigid Pecking Order

Pecking order may be a term that you associate with chickens or even at work. If you have heard of a pecking order in the realm of business or employment your understanding of the term would be correct -a pecking order is a hierarchy within a flock of birds and, in this case, it relates to Chickadees. In the pecking order of Chickadees, the more aggressive an individual is, the higher or further along the pecking they are. Individuals at the top of the pecking order earn better access to food and safer places to occupy within the shrubs and territories where the group is colonizing. Adults also typically pair and then mate according to pecking order, with the highest ranked male pairing with the highest ranked female, and so on. Individuals will continue to vie for better spots in the pecking order, and therefore mating pairs may change and evolve as individuals outcompete and displace others.

3. They Communicate With About 15 different Songs and Calls

Black-capped Chickadees have several other calls in addition to the highly recognizable call for which they are named “chicka-dee-dee”. One call sounds like a high pitched “see” which is used to warn others of an approaching predator. When others birds hear this call, they freeze and do not resume their activity until an “all clear” chicka-dee call is heard. Black-capped Chickadees will also emit a “gargling” call when a bird of a lower rank comes too close to a bird of a higher rank. A personal favourite is their ““hey sweet-ie” song which also sounds like “cheese-bur-ger”. This song has caused some staff at The Land Between to refer to Black-capped Chickadees as “the cheeseburger birds”.

4. The More dees in a Chicka-dee-dee Call, the Higher the Threat Level

The chicka-dee-dee-dee call is used to warn others about predators and threats. The greater the number of dees in the call, the greater the threat is.

5. They Provide an Important Form of Natural Pest Control

Approximately 90% of a Black-capped Chickadee’s diet in the summer is composed of insects, many of which are considered pests in forests and orchards. Included in the summer diet of the Black-capped Chickadee are caterpillars, weevils and lice, the eggs, larvae and pupae of various other insects, caterpillars and spiders.

6. It is the Official Provincial Bird of New Brunswick

The Black-capped Chickadee has been the official provincial bird of New Brunswick since 1983. It was also in the running (top 5) to be Canada’s Official Bird in 2016, but lost out to the Canada Jay. Other official provincial birds include the Steller’s Jay (British Columbia), the Sharp-tailed Grouse (Saskatchewan), and the Common Loon (Ontario).

7. They Know How to Handle the Cold

In an effort to conserve energy at night, Black-capped Chickadees will drop their body temperature by 10-12 degrees below daytime temperatures. They will also “lift” their feathers, puffing them out away from their bodies to trap warm air close to their bodies.

Each animal in your neighbourhood has a unique way of navigating the world and communicating within the world. Get to know more birds and wildlife in The Land Between by volunteering for a Citizen Science program, watching our webinars, or simply observing nature in your immediate area.
