House Martins are the birds with white rumps that build mud nests on the eaves of buildings often in colonies averaging five nests. They will readily use artificial nests and this may encourage other birds to nest nearby.
These nests should be sited underneath the eaves of your house or outbuildings.
Please note: The house martin nest double packed weight is more than 2kg and thus it is not possible to send this by standard post and is cheaper to send by courier. Note that no matter how many of the double nests you order there is only one courier charge.
