Description
A presentation of the first quantitative estimates of emission rates for chemical signals in crested auklets. Volatile emissions from live birds were captured in a purified airstream onto polymer traps. Traps were eluted with methanol and analyzed with gas chromatography-mass spectrometry. The result is an index of volatile chemical emissions within a small population of wild crested auklets. Males and females did not differ in their emissions rates. There was a sevenfold difference between minimum and maximum emission rates. Ticks were abundant in the colony, however only 2% of the aukelts from Big Koniuji Island, Alaska, USA were infected. Auklets heavily infected with ticks had the lowest chemical emission rate.
