The Nesting Habits of Coal Tits
Coal tits are small, lively birds that are prevalent throughout Europe. These birds are known for their striking black and white markings, charming chirps, and delightful nesting habits.
In this article, we’ll explore the nesting preferences and behaviors of coal tits, from their preferred nesting habitats to their use of nesting materials and construction techniques.
Preferred Nesting Habitats
Coal tits have a wide range of nesting preferences, but trees are their preferred nesting sites. Trees provide ample space, shelter, and support, and coal tits take advantage of this in a variety of ways.
They are known to make their nests in tree cavities, holes, or even burrows, depending on the availability and accessibility of the nesting material.
Nest Boxes
Nest boxes are a popular choice for coal tits, particularly in urban areas where it may be challenging to find suitable nesting materials. Coal tits prefer nests that have a small entrance and face northeast.
The nest box should also provide enough nesting material, including moss, wool, grass, fur, spider webs, and feathers, to make the coal tits feel secure and comfortable.
Dreys
Dreys are another popular choice for coal tits.
Dreys are nests that are usually made from twigs, leaves, and other plant material.
They are not constructed on trees, but rather in the branches of trees or on a tree’s trunk. Coal tits will select dreys that offer a good balance of shelter, accessibility, and comfort.
Roots
Coal tits will frequently make their nests in the roots of trees. The roots provide an excellent base for the nest and offer ample protection from the elements.
However, these types of nests are more challenging to access and build, requiring a little more effort and patience.
Burrows
Coal tits will also make use of burrows as nest sites.
Burrows created by other animals, such as squirrels and woodpeckers, are convenient and can be found in a variety of environments.
Coal tits will readily move in and nest inside the burrows, taking advantage of the hard work and protection offered by these pre-existing structures.
Walls and Rocks
Finally, coal tits are known to nest in walls and rocks. A suitable crack or crevice in a rock face or wall can provide the perfect foundation for a nest.
These sites offer excellent protection from predators and the elements, and the nest itself can be constructed using a variety of nesting materials, including moss, lichen, and feathers.
Nest Appearance
Coal tits’ nests are usually cup-shaped, with a diameter of around 7 cm. The nests are composed of a variety of materials, such as moss, wool, grass, fur, spiders webs, and feathers, which are tightly woven to make a compact and cozy nest.
The nest is typically lined with feathers and fur to provide warmth and softness for the eggs and nestlings.
Phenology
March and April are the months when coal tits begin their mating and courtship rituals. During this period, males will establish territories and begin collecting nesting materials.
Coal tits generally lay between 5 and 12 eggs, which take around 14 days to incubate. After hatching, the nestlings will remain in the nest for a further 17 to 21 days while they are fed by both parents.
Nest Construction
The construction of the nest is primarily undertaken by the female. She will select the site for the nest and collect the nesting material.
The nest materials are then arranged in a circular fashion to create the walls of the nest. Finally, she will add a fluffy lining of feathers and fur to finish off the cozy interior.
Tree Preferences
Coal tits prefer to nest in conifers, such as pine, spruce, fir, and larch. The dense foliage provides ample privacy and protection, making it an attractive option for nesting.
However, coal tits also nest in deciduous trees, such as birch and oaks, particularly in habitats where conifers are less common. Use of
Nest Boxes in Urban and Suburban Areas
In urban and suburban areas, coal tits have been known to use nest boxes.
These boxes offer easy accessibility and a secure environment for the nestlings. Coal tits will also take advantage of garden feeders and other human-provided food to sustain themselves during the nesting season.
Winter Nesting
During the winter months, coal tits will frequently use empty nest boxes and coniferous forests as a source of shelter. These locations provide ample protection from the elements and are ideal overwintering sites.
Conclusion
In conclusion, coal tits are industrious and resourceful birds with a wide range of nesting preferences. They take advantage of a range of environments and nest sites, from trees, roots, rocks, walls, and burrows.
Coal tits’ nests are well-structured, cup-shaped, and composed of a variety of nesting materials. Nest boxes are popular nesting sites, particularly in urban and suburban areas, where coal tits face more limited nesting options.
The construction of the nest is primarily undertaken by the female, who arranges the nesting materials in a circular fashion and then adds a lining of feathers and fur. Conifers are preferred nesting trees, but deciduous trees are also popular.
Winter nesting occurs in empty nest boxes and coniferous forests.
Breeding Behavior and Care
Coal tits are beautiful, active birds with a fascinating breeding behavior. Breeding can occur from late winter to early summer, with the female laying eggs in clutches of between five and 13, with 7-11 eggs being the average.
Second or even third broods can occasionally occur, but typically have fewer eggs. Once the eggs are laid, the female begins the incubation process alone.
The male is responsible for feeding the female during this time, bringing her food regularly. After approximately 14 days of incubation, the eggs hatch, revealing tiny and helpless chicks.
The parents continue to work together to care for the chicks, with the male taking on more of the feeding duties while the female remains in the nest with the young. The chicks stay in the nest for around three weeks, after which time they are fledged and ready to leave the nest.
Coal tits exhibit family grouping behaviors even after fledging. Coal tits are still dependent on their parents for around two weeks after leaving the nest.
They continue to receive care and attention from their parents until they are fully independent. It is also common for coal tits to produce multiple broods in a single season.
Nest Abandonment
Coal tits may abandon their nests for various reasons. The most common reasons for nest abandonment are the death of their mate, nest invasion, or the threat of a predator.
When a mate dies, the surviving bird may lose interest in the nest and abandon it to look for a new mate.
Ground Nesting
Coal tits typically nest in trees, often using existing cavities or nest boxes. Ground nesting is uncommon in coal tits, but it can happen.
In these cases, they usually use mouse burrows, tree roots, or rotting logs as the foundation for their nest. Ground nests are generally less sturdy than aerial nests and are more vulnerable to predators.
Attracting Coal Tits
To attract coal tits, you should provide an environment that suits their needs and preferences. This includes the provision of suitable nesting sites, food, and suitable foraging areas.
Food Preferences
Insects make up a significant portion of a coal tits’ diet, particularly during the breeding season. Providing protein-rich foods, such as mealworms, is an excellent way to attract these birds.
Additionally, offering small seeds, nuts, and suet can also be beneficial. Coal tits have a particular preference for consuming aphids, so encouraging these insects in your garden can attract them to your property.
Nest Box Preferences
Nesting boxes are an excellent way to lure coal tits to your garden, particularly if you live in an urban or suburban area. These box designs should have small entrances and face northeast.
Because of their nest height preferences, situate them at a height of around two to eight meters to ensure the best chance of attracting coal tits.
Tree Preferences
Coal tits prefer to nest in conifers, such as pine trees, with abundant needles that provide insulation and protection. Additionally, they also nest in deciduous trees, particularly birches.
Incorporate these trees into your garden and provide suitable nesting boxes, food sources, and sheltered areas to create an ideal habitat that will attract coal tits.
Garden Suitability
Creating the right environment in your garden involves providing tree cover as well as areas where coal tits can forage. Planting shrubs, trees, and wildflowers creates shelter and food sources, and you should provide a variety of surface types, from well-manicured lawn to loose soil, where coal tits can find food.
By providing this mix of shelter and foraging opportunities, you are likely to attract coal tits to your garden.
