  • Data were collected from small skylarks (Alauda gulgula) and twits (Acanthis flavirostris) during the reproduction seasons of 1998-1999 in alpine meadow in order to test and confirm their reproductive patterns.The results were showed:1)In the small skylarks,the level of hatching asynchrony was low (1 d);a egg mass did not consistently vary with the laying order,but the last-laid egg mass was maximal;the hatch order had a significant positive impact on the nestling growth rate (P<0.01) and had little impact on the fledged mass and nestling period of young (P>0.05).2)In the twits,the level of hatching asynchrony was higher asynchronously (2-3 d);the egg mass increased significantly with the laying order (P<0.05);the hatch order had little impact on the growth,fledged mass and nestling period (P>0.05).The results analysis suggests that the small skylarks and twits in alpine meadow select both hatching asynchrony and brood enlarge strategy as the breeding patterns.

Effects of Hatching Behavior on Offspring Quality in Two Species Passerines

Abstract: Data were collected from small skylarks (Alauda gulgula) and twits (Acanthis flavirostris) during the reproduction seasons of 1998-1999 in alpine meadow in order to test and confirm their reproductive patterns.The results were showed:1)In the small skylarks,the level of hatching asynchrony was low (1 d);a egg mass did not consistently vary with the laying order,but the last-laid egg mass was maximal;the hatch order had a significant positive impact on the nestling growth rate (P<0.01) and had little impact on the fledged mass and nestling period of young (P>0.05).2)In the twits,the level of hatching asynchrony was higher asynchronously (2-3 d);the egg mass increased significantly with the laying order (P<0.05);the hatch order had little impact on the growth,fledged mass and nestling period (P>0.05).The results analysis suggests that the small skylarks and twits in alpine meadow select both hatching asynchrony and brood enlarge strategy as the breeding patterns.
