Wildlife Welfare

Wild House Martin Colony Welfare

House martins are declining summer migrants whose welfare depends on mud availability for nest construction and insect abundance for chick feeding.

Key Facts

House martin populations have declined by 37% since the 1970s in the UK
They build mud nests under the eaves of buildings requiring wet mud access
Nest destruction by householders removes years of accumulated nest structure
Artificial nest cups installed under eaves provide supplementary breeding sites
Chick food comprising aerial insects is reduced by pesticide use

Welfare Considerations

House martin welfare during breeding depends on access to mud for nest construction and abundant aerial insects for chick feeding. Loss of muddy ponds and puddles combined with insect decline is reducing breeding success, with nest protection by householders being a simple welfare intervention.

What You Can Do

Preserve existing house martin nests on your property - they are legally protected
Install artificial house martin nest cups if natural nests are absent
Create a muddy patch in your garden to provide nest-building material
