Abstract Background Global warming caused trophic mismatch has affected the breeding success, and even the survival, of some bird species. The ability of birds to accelerate their reproduction onset in the warmer spring could be critical to the survival of some species. The activation of the reproductive endocrine axis in birds is a key physiological process that determines the onset of reproduction. Could birds change the HPG axis endocrine rhythm under the temperature rising condition? Methods Using plasma LH level as an indicator of initiation of the reproductive endocrine and artificially controlling temperature, we compared variations in the timing of activation of the reproductive endocrine axis in response to temperature in two Chinese bird species, the Eurasian Skylark (Alauda arvensis) and the Great Tit (Parus major) at both the population and individual levels. Results At the population level, temperature only significantly influenced LH level in the Eurasian Skylark, and had no significant effect ...
