This Week: Northern Mockingbird
The Northern Mockingbird is a medium-sized songbird, measuring 9-11 inches long, with a long thin bill and long legs. They have a distinctive appearance with grayish plumage, paler on the breast and belly, and two white wingbars on each wing.
Their wings are short and broad, making their tail seem particularly long in flight. You can spot them perched high and exposed on trees, bushes, fences, and wires.
Northern Mockingbirds are very vocal and have dozens of songs and imitations, including the calls of other birds and even the voices of frogs and toads. They're known to mimic music and machinery too!
They often mimic the call of red-tailed hawks, which can be confusing for birders. John James Audubon was so impressed by this bird's singing ability that he wrote about it in "Birds of America".
These birds are aggressive and will forcefully chase off intruders in their territory. They'll attack anything that approaches their nest, including cats and humans.
Their diet consists mainly of insects and berries, with a focus on insects in late spring and summer. They'll eat beetles, grasshoppers, caterpillars, ants, and wasps, and occasionally crayfish and lizards.
Habitat and Distribution
The northern mockingbird's habitat is quite varied, but it generally prefers open areas with sparse vegetation. This is because it likes to forage for food in short grass.
In the eastern regions, you can often find these birds in suburban and urban areas like parks and gardens. They seem to have a special affinity for mowed lawns with shrubs nearby for shade and nesting.
In the western regions, desert scrub and chaparral are among their preferred habitats. They tend to reside in the same habitats year-round, and don't seem to mind the occasional human presence.
Distribution and Habitat

The mockingbird's distribution is quite impressive, covering a vast range from southern Canada to southern Oregon, and south through the continental United States, the Greater Antilles, and most of Mexico.
It's a year-round resident in its range, but birds in the northern portion often move south during winter. The mockingbird's migratory behavior is not well understood, especially in the northern parts of its range.
Small numbers of northern mockingbirds have been recorded in southeastern Alaska and even as far away as Britain, where one individual made a remarkable journey from Devon to Northumberland in 2021.
In the 19th century, the mockingbird's range expanded northward to provinces like Nova Scotia and Ontario, and states like Massachusetts, although sightings were sporadic.
Regions that received an influx of mockingbirds within the first five decades of the 20th century include Maine, Vermont, Ohio, Iowa, and New York.
The mockingbird prefers open areas with sparse vegetation, and in eastern regions, it's often found in suburban and urban areas like parks and gardens.

It has a particular affinity for mowed lawns with shrubs nearby for shade and nesting. In western regions, desert scrub and chaparral are among its preferred habitats.
When foraging for food, the mockingbird prefers short grass. It doesn't nest in densely forested areas and generally resides in the same habitats year-round.
Bird Habitats
The Northern Mockingbird's habitat preferences are quite interesting. They generally prefer open areas with sparse vegetation.
Mockingbirds can be found in a variety of habitats, including suburban and urban areas like parks and gardens in the eastern regions. In western regions, they prefer desert scrub and chaparral.
They have a special affinity for mowed lawns with shrubs nearby for shade and nesting. In fact, they often reside in the same habitats year-round.
To attract Northern Mockingbirds, try setting out raisins or grapes, as they prefer insects and small fruits to nuts and seeds. They also enjoy birdbaths, especially if the water's moving.
Behavior and Adaptation
The northern mockingbird is a bold bird that's not afraid to stand up for itself. They aggressively defend their nests and surrounding areas against other birds and animals, and will even summon neighboring mockingbirds to join the defense if a predator is persistent.
In fact, these birds will attack much larger birds, including hawks, and have even been known to target humans. One notable incident in Tulsa, Oklahoma, involved a postal carrier who received a warning letter to residents after the mockingbirds defended themselves against the carrier.
Despite their fearless nature, northern mockingbirds are also quite social and will gather to watch as their fellow mockingbirds drive away an intruder. They're also skilled at utilizing artificial lighting to feed their young in urban areas, allowing them to thrive in environments where food may be scarce.
Urban Habitat Adaptation
The northern mockingbird is a species that's adapted surprisingly well to urban habitats. In fact, more of them live in cities than in rural areas, making them an "urban-positive" species.
One reason for this is that urban environments are more predictable than rural ones. Urban birds are more likely to return to the nest where they had a successful breeding season the previous year, and avoid those where breeding was unsuccessful.
Urban birds also have an advantage when it comes to food availability. They can take advantage of artificial lighting to feed their young into the night, which is a big help in residential neighborhoods.
However, urban living also has its downsides. Northern mockingbirds in cities like Baltimore and Washington, D.C. are more susceptible to lead poisoning.
Here's a comparison of urban and rural habitats:
This is likely due to lower food availability and travel costs in rural areas. Urban birds seem to have an easier time finding food and navigating their surroundings.
Overall, the northern mockingbird is a remarkable example of adaptability in the face of changing environments.
Behavior
Northern mockingbirds are bold birds that don't back down from a fight. They aggressively defend their nests and surrounding areas against other birds and animals.
Mockingbirds have been known to summon help from neighboring territories by distinct calls, gathering other birds to drive away an intruder. They'll even attack much larger birds, like hawks, and have been known to target humans.
In addition to defending their territories, mockingbirds are also skilled at foraging for food. They spread their wings in a peculiar two-step motion to display white patches while searching for food on the ground or in vegetation.
This behavior is still a topic of debate among ornithologists, with some thinking it's a way to intimidate predators or prey, while others believe it's just a way to slow down.
Northern mockingbirds are also fiercely protective of their young, with females incubating eggs for about 11 to 14 days before they hatch. After that, the offspring become independent in just 10 to 15 days.
Mockingbirds are also known for their complex social dynamics, with males singing songs to attract females and defend their territories. Unmated males will often sing more frequently and in more directions than mated males.
Remarkable Mimics

Mockingbirds are known to spout endless strings of songs, often dozens in a row. They may do a perfect imitation of another species' call, repeating the sound rapidly up to 10 times in a row before switching to a different sound.
These birds use their impressive imitation skills to outline the boundaries of their turf to other mockingbirds. They have song posts in various places around the edge of their territory, where they go to sing.
Male mockingbirds sing through the day and night, particularly during the breeding season, while females sing much more softly.
Conservation and Threats
Northern mockingbirds face a range of threats that can impact their populations. Adult mockingbirds can fall victim to birds of prey such as great horned owls, screech owls, and sharp-shinned hawks.
Some predators are more brazen than others, with scrub jays known to kill and eat mockingbirds. Snakes rarely capture incubating females, but they can be a threat to eggs and nestlings.
Fledglings are vulnerable to domestic cats, red-tailed hawks, and crows, which can be a significant threat to their survival. Eggs and nestlings are also consumed by other birds, including blue jays, fish crows, and American crows.
Winter storms have played a significant role in declining mockingbird populations in some areas, such as Ohio, Michigan, and Minnesota. In these regions, the storms have limited the birds' ability to expand their range.
Dry seasons also affect mockingbird populations, as seen in Arizona, where they can impact the birds' ability to survive and thrive.

Sounds and Calls
The northern mockingbird's vocal abilities are truly impressive. It can mimic a wide range of sounds, from other birds to animals and even man-made noises.
One of the most striking aspects of the mockingbird's mimicry is its ability to imitate the songs of other birds, such as the Carolina wren, northern cardinal, and eastern bluebird. It can also reproduce the calls of birds like the northern flicker and great crested flycatcher.
In addition to bird songs, the mockingbird can mimic sounds from other animals, such as cats, dogs, frogs, and crickets. It can even replicate the sounds of artificial items, like unoiled wheels and car alarms.
The mockingbird's mimicry is not limited to its ability to imitate sounds, but also its ability to use them in different contexts. For example, it uses its "hew call" for potential nest predators, conspecific chasing, and various interactions between mates.
The mockingbird has four recognized calls: the nest relief call, hew call, chat or chatburst, and the begging call. The hew call is mainly used by both sexes for potential nest predators, conspecific chasing, and various interactions between mates.
Chats and chatbursts have some key differences. Chats are year-round, while chatbursts occur in the fall, and chatbursts appear to be used in territorial defense in the fall.

Breeding and Nesting
Northern mockingbirds are known to form long-term pair bonds, with some pairs staying together for up to 20 years.
These birds are territorial and will fiercely defend their territories from other mockingbirds and predators.
Female mockingbirds typically lay 3-5 eggs per clutch, which are white and speckled with brown.
Both parents take turns incubating eggs for about 12 days, with the female doing most of the incubation.
After the eggs hatch, both parents feed and care for their young, which leave the nest after about 10-14 days.
Northern mockingbirds are known to reuse their nests year after year, often adding new material to repair and maintain them.
