Summary
Key
Meadow Pipit habitats such as moorland are not covered well by the
CBC, but the decline in the CBC trend may warrant conservation attention,
especially because it was accompanied by a contraction range from
lowland England (Gibbons et al. 1993). Meadow Pipits are partial
migrants and conditions on the species' Iberian wintering grounds
have been linked to the decline, as have losses of marginal land from
breeding habitats (Gibbons et al. 1993). Nest failure rates
at the 12-day nestling stage have declined from 30% to 12%, which
may reflect the loss of birds from suboptimal areas. Changes in laying
date are related to climate change (Crick & Sparks 1999).
