... 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...

...Heather Williams SUMMARY As do many songbirds, zebra finches sing their learned songs while performing a courtship display that includes movements of the body, head and beak. The coordination of these display components was assessed by analyzing video recordings of courting males. All birds changed...

... 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...

...H. C. BENNET-CLARK During burrow digging by the mole cricket Scapteriscus acletus Rehn and Hubbard, the burrow is enlarged and shaped in a series of digging cycles, each lasting 1–2min, and song chirps are produced after every cycle. The song becomes up to 18 dB louder and acoustically purer during...
