... health, we monitored daily activity behaviour, recorded song and cheek patch size in males, and measured body size and hormone levels. As compared with controls under 12 h light:12 h darkness (12 h:12 h LD), both P and F1 pairs showed a compromised reproductive success, as evidenced by fewer fledglings...

... recorded male song on reproductive development in migrants and residents on a naturally increasing photoperiod. Second, we tested the sensitivity of migrant-specific life history events (fattening and pre-alternate molt) to song treatment. After 82 days, residents had higher luteinizing hormone and greater...

... are smooth and appear to be sealed with saliva. The song has a mean centre frequency of 3.2 kHz and is made up of variable-length trills of pulses of mean duration 15.8 ms. Many song pulses had smooth envelopes and their frequency did not vary by more than ±40 Hz from the centre frequency, with a relative...
