Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Aves
Order: Passeriformes
Family: Paridae
Genus: Parus
Species: Parus bicolor

Geographic Range

Tufted titmice are only native to the Nearctic region. They are common east of the Great Plains in the woodlands of the southeastern, eastern, and midwestern United States, and in southern Ontario. Tufted titmice were once known only from the Ohio and Mississippi river drainages. Since the 1940's they have expanded throughout the eastern seaboard and now continue to expand their range northwards into Canada.

Biogeographic Regions:
nearctic (native ).

Habitat

Tufted titmice prefer deciduous woodlands, especially moist woodlands found in swamps and river basins. They are also common in wooded residential areas and city parks.

These animals are found in the following types of habitat:
temperate ; terrestrial .

Terrestrial Biomes:
forest .

Other:
suburban ; riparian .

Physical Description

Length
15 to 17 cm
(5.91 to 6.69 in)


Wingspan
23 to 28 cm
(9.06 to 11.02 in)


Tufted titmice are 15 to 17 cm long and have wingspans of 23 to 28 cm. Both males and females have white undersides, gray backs, rusty-brown sides, pointed crests on their heads, and large dark eyes.

Some key physical features:
endothermic ; homoiothermic; bilateral symmetry .

Reproduction

Breeding interval
Tufted titmice breed during the warm months of the year, they may have one or two broods each season. The young of the first brood may help care for nestlings of the second brood.

Breeding season
Tufted titmice breed from March to May.

Eggs per season
5 to 8; avg. 6.50

Time to hatching
17 days (high)

Time to fledging
17 to 18 days

Age at sexual or reproductive maturity (female)
1 years (average)

Age at sexual or reproductive maturity (male)
1 years (average)

Breeding takes place between March and May. Five to eight brown-speckled white eggs are layed in nests 3-90 feet up. Nests are formed in natural tree cavities, abandoned woodpecker holes, bird boxes, hollow metal pipes, and fence posts and are then filled with wool, moss, cotton, leaves, bark, hair, etc. They even pluck hairs from live woodchucks, squirrels, opossums, and humans near nest sites. Eggs are incubated by the female for 13-17 days, and the young climb down from the cavities when 17-18 days old. Both parents feed the young. There are sometimes two broods a season and the young of the first brood often help care for the second. Tufted titmice are able to breed in the year following their hatching.

Key reproductive features:
iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous .

Both parents feed the young nestlings. In the first 4 days after the young hatch, males feed them much more often than do females. After a while both parents share the job until the young are ready to leave the nest. It is not uncommon for the pair to have nest helpers. These may be their own young or other birds. They assist in feeding the nestlings.

Parental investment:
pre-fertilization (provisioning, protecting: female); pre-hatching/birth (protecting: male, female); pre-weaning/fledging (provisioning: male, female, protecting: male, female).

Lifespan/Longevity

Extreme lifespan (wild)
13 years (high)

Average lifespan (wild)
2.10 years

The average lifespan of tufted titmice is 2.1 years. This number is relatively low because most tufted titmice die as nestlings. Once they reach adulthood, tufted titmice are likely to live for more than 2 years. The longest these birds have been know to live in the wild is 13 years.

Behavior

Tufted titmice are active birds often seen flitting about in trees and hanging upside down while searching beneath twigs for insects. They are active during the daytime and do not migrate extensively, remaining in residence throughout the winter. They are fairly confident birds and can be trained to come at the sound of human voices and take food from their hands, though not as easily as their bold cousins, black-capped chickadees. They travel and roost during the winter in small flocks. Tufted titmice store food under bark or under objects on the ground. Males are dominant over females and they form pairs that persist until the death of one of the mates. Pairs separate from winter flocks in preparation for mating by February.

Key behaviors:
arboreal ; flies; diurnal ; motile ; sedentary ; territorial ; social .

Communication and Perception

Titmice calls sound like: "peto, peto, peto" or "peter, peter, peter", and "day-day-day". One can call them to you by imitating this call. There are 10 different known calls of tufted titmice. The calls are generally divided into 2 groups. One group is made up of calls that have a very low frequency and the others have a very high frequency. The three calls in the group of high-frequency calls are usually associated with agressive behavior. Tufted titmice also communicate among themselves using body posture and movements.

Communicates with:
visual ; acoustic .

Perception channels:
visual ; tactile ; acoustic ; chemical .

Food Habits

Tufted titmice eat a wide variety of insect and invertebrate prey, including caterpillars, moths, flies, insect eggs, snails, and spiders. They also eat berries and seeds. They hold seeds under their feet on branches and crack them with their sharp bills. Tufted titmice are common at bird feeders where they eat seeds, especially sunflower seeds, suet, and other offerings.

Primary Diet:
omnivore .

Animal Foods:
eggs; insects; terrestrial non-insect arthropods; mollusks.

Plant Foods:
seeds, grains, and nuts; fruit.

Predation

Known predators

Tufted titmice nestlings are preyed upon by nest predators such as snakes, raccoons, skunks, opossums, and squirrels. Adults are preyed upon by cats and predatory birds such as hawks and owls. In the eastern United States the most common birds of prey that hunt tufted titmice are sharp-shinned hawks and Cooper's hawks. Tufted titmice give off high-pitched alarm calls when hawks are seen flying overhead.

Ecosystem Roles

Tufted titmice nestlings are preyed upon by a number of animals. They also control insect populations and distribute nuts by carring them away to eat them.

Economic Importance for Humans: Negative

There are no negative impacts of tufted titmice on humans.

Economic Importance for Humans: Positive

Tufted titmice help to control the population of certain insects as well as helping trees by distributing their seeds.

Ways that people benefit from these animals:
controls pest population.

Conservation Status

US Migratory Bird Act: [link]:
Protected.

Tufted titmice ar fairly common throughout the eastern United States.

Other Comments

Tufted titmice are also known as crested titmice, crested tomtits, pete birds, tufted chickadees and tufted tits. Black-crested titmice, found only in Texas and Oklahoma, were considered to be a separate species until 1983. They now are considered to be a subspecies of tufted titmice, Parus bicolor castaneifrons.
