Birdhouses serve several important purposes for both birds and people. At their core, birdhouses provide birds with a safe place to build nests and raise young. However, they can also help attract desired bird species to a yard, allow people to observe bird behavior and reproduction, and even help support conservation efforts for threatened species. Understanding the multifaceted purposes of birdhouses can help bird enthusiasts better utilize and appreciate these helpful backyard structures.
Providing Shelter and Nesting Sites
The primary reason for a birdhouse is to give birds a place to build their nests and raise their young. In nature, birds nest in tree cavities, nests of other species, and rock crevices. However, human activities like logging, forest clearing, and development have reduced natural nesting sites. Birdhouses help supplement these losses and give desired bird species a safe place to reproduce.
Bird species that commonly use birdhouses to nest include bluebirds, chickadees, nuthatches, wrens, titmice, swallows, and some types of woodpeckers. Cavity nesters like these birds cannot excavate holes in wood or build open cup nests, so they rely on existing cavities. Birdhouses mimic these natural cavities with enclosed spaces accessible through an entry hole. They should provide dry, well-insulated shelter for eggs, chicks, and parents.
Birdhouses protect breeding birds from predators and exposure to weather. The enclosed structure with a small opening deters larger animals. Proper birdhouse placement and design minimizes risks like temperature extremes, moisture, and strong winds. With a safe nesting site, adult birds can focus more energy on incubating eggs and finding food.
Choosing a Birdhouse Design
The best birdhouse design depends on the target species. Consider factors like:
- Entrance hole size – Should match the birds’ body size to exclude predators
- Interior dimensions – Large enough for the species but not too big
- Height above ground – Varies by species and predator risk
- Construction materials – Avoid treated woods with chemicals
- Other features – Perches, ventilation, cleanouts, etc.
Multiple birdhouses with different features may be necessary to attract several desired species to a yard. Place houses in suitable habitats for each species.
Attracting Birds to a Yard
In addition to supporting nesting and reproduction, birdhouses help attract birds to a yard. Seeing favored birds up-close is one reason many people install birdhouses. The activity coming to a nesting box provides enjoyment and fosters an appreciation of nature.
Birdhouses placed in a yard or garden complement other birdfeeding practices. Food from feeders gives birds energy, while birdhouses facilitate reproduction to increase populations. Strategically placing multiple birdhouses and feeders allows a diversity of species to flourish.
Monitoring occupied birdhouses provides excellent opportunities to observe bird behavior, nesting habits, parenting activities, and chick development. Seeing this annual cycle up close helps people connect with nature.
Bluebird houses are popular partly because bluebirds are visually appealing. However, even birdhouses for plain-colored chickadees or nuthatches let people see fascinating nesting behaviors. Enjoyment from observing birdhouse activity fosters ongoing support for creating bird-friendly spaces.
Tips for Attracting Birds
Follow these tips to maximize the bird attraction benefits of birdhouses:
- Choose appropriately sized, well-constructed houses for target species
- Place houses in suitable habitat with food, water, and materials nearby
- Include multiple birdhouse types to attract several species
- Add feeders with favored foods to provide supplemental energy
- Include native plants that supply fruits, seeds, cover, and nest materials
- Limit pesticide use so birds can find natural insect foods
Observing Birds and Nesting Biology
Observing the birds that visit a yard is an excellent recreational pastime. Birdhouses create even more fascinating viewing opportunities by letting you watch birds build nests, lay eggs, raise chicks, and exhibit parenting behaviors.
Monitoring an active birdhouse provides a personal connection to nature’s annual cycles. Seeing the nest progress from construction to eggs to chicks gives insight into key aspects of avian reproduction:
- Nest building – Collection of materials and construction of the nest cup
- Egg laying – Observation of clutch size and egg color
- Incubation – Taking turns warming the eggs until hatching
- Feeding chicks – Frequent visits with food items for the growing chicks
- Fledging – Exit of young from the nest as they learn to fly
Birdhouse observation allows you to enjoy each phase of this nesting cycle. Keeping notes and photos from season to season creates a long-term record showing your local birds’ productivity.
Ethical Birdhouse Monitoring
Although birdhouses create viewing opportunities, it’s important to observe nests ethically to limit disturbance:
- Be discreet when approaching to minimize stress
- Keep observation sessions brief, especially when chicks are present
- Avoid visiting in poor weather when parents are needed in the nest
- Do not handle eggs or chicks
- Wait until autumn to clean out old nests
With careful observation, you can gain educational benefits from birdhouses without negatively impacting their residents.
Supporting Scientific Research
In addition to recreational observation, data collected from birdhouses can support scientific research. Detailed monitoring provides biologists with valuable information on topics like:
- Reproductive success rates
- Population changes
- Effects of environmental factors
- Impacts of climate change
- Outcomes of conservation programs
Participating in nest box monitoring programs like NestWatch allows hobbyists to contribute their birdhouse observations to a national database used for research and conservation.
Having many citizen scientist participants allows collection of large amounts of data over broad geographical areas. Recording birdhouse occupancy rates and reproductive outcomes helps scientists track population trends and assess conservation needs for threatened species.
Participating in Nest Box Programs
If interested in using your birdhouse observations for science, look for citizen science programs in your area. Options include:
- NestWatch – A nationwide nest monitoring program through the Cornell Lab of Ornithology
- Bluebird Society – Provides guidance on bluebird conservation efforts
- Local Audubon groups – May coordinate regional nest box programs
- Universities – Often study local bird populations and conservation
Contributing data to coordinated monitoring networks amplifies the value of birdhouses as both recreational amenities and scientific tools.
Supporting Endangered Species
In some cases, birdhouses also provide vital habitat for threatened bird species. Species of special concern may have specific nesting requirements that cannot be met in natural areas degraded by human impacts.
Putting up specialized birdhouses is one way community scientists can help endangered species recovery. For example, in British Columbia, nest boxes with small openings installed in wetlands helped attract the Western Screech Owl, which became locally endangered after losing nesting cavities in damaged forest habitat.
Likewise, Wood Duck nest boxes placed over waterways helped bolster populations of this forest duck after logging and wetland drainage reduced natural cavity nesting sites. Specific birdhouse designs catered to the needs of threatened species can expand usable habitat and breeding opportunities where natural sites are lacking.
Special Features of Endangered Species Birdhouses
To effectively support an endangered species, specialized birdhouses should match key nesting requirements:
- Size – Dimensions fit the species
- Placement – In preferred habitat
- Materials – Durable, long-lasting
- Entrance – Limits larger competitors
- Ventilation – Important for some species
Before installing any specialized houses, research the needs of the target species. Follow guidelines from conservation agencies to maximize benefits.
Enjoying Family Activity
Installing and monitoring birdhouses also provides rewarding family-friendly outdoor activities. Parents can pass on an appreciation of nature and conservation by involving kids in creating and learning about birdhouses.
Children take pride in constructing their own birdhouse. Kits allow kids as young as four or five to use child-safe hammers to build an attractive birdhouse. With adult supervision, older kids can also use tools like saws and drills to create more complex birdhouse designs.
Decorating a customized birdhouse cultivates creativity. Kids enjoy painting fun patterns or stenciling bird images on their birdhouse. Whimsical elements like pretend doors and windows add playful elements to a backyard birdhouse.
Once the birdhouse is up, children get excited to check on baby birds hatching in “their” house. Seeing parenting birds feed worms to chicks teaches kids about bird family roles and nurturing behaviors.
The learning continues as fledglings grow big enough to leave the nest. Kids take pride in this moment after patiently waiting while “their” baby birds grew.
Engaging Children with Birdhouses
Follow these tips to get maximal learning and enjoyment from birdhouses with kids:
- Choose child-friendly construction projects for their abilities
- Decorate together to highlight creativity and individuality
