2011-05-11 Chick sex swayed by farm grazing
Grazing by farm animals
can skew the sex ratio of bird chicks, a UK research team has found -
potentially affecting the species' prospects.
They found that meadow pipits Anthus pratensis produce fewer males if land near
their nests is either grazed heavily or not at all, with light grazing
bringing more males.
The reasons behind it are unclear, they add, and should be researched further. |
