The eaves of a house may sound an unlikely place to look for wildlife, but you may find many species living there. In the eaves, the house roof projects beyond the wall it supports creating a sheltered, often warm place.
Insects and other invertebrates may hide or even hibernate up here. House martins build their mud homes in eaves, and you can encourage them by putting up artificial nests. Starlings and house sparrows may also take up residence in nestboxes in the eaves.
Bat boxes can also be hung up here and may be used as summer roosts.
Make the most of your garden
- Put up a nestbox with a 32 mm entrance hole if you want to attract house sparrows.
- Put up a nestbox that is about 30% larger and with a hole of 45 mm for starlings.
- Hang several bat boxes facing different directions if possible. They may be used at different times of year depending on conditions.
Sparrows are quite aggressive. They may harass other birds and steal their food or nests. Do not hang a nestbox intended for sparrows near to house martin nests.
