MARC recordOn the importance of estimating detection probabilities from at-sea surveys of flying seabirds / Christophe Barbraud, Jean-Baptiste Thiebot.
| Title: | On the importance of estimating detection probabilities from at-sea surveys of flying seabirds / Christophe Barbraud, Jean-Baptiste Thiebot. |
| Author(s): | Barbraud, Christophe. Thiebot, Jean-Baptiste. |
| Date: | 2009. |
| In: | Journal of Avian Biology. (2009.), Vol. 40(6) (2009) |
| Abstract: | Uses distance sampling method from line-transects to estimate detection probability for flying seabirds, and tests whether distance from ship and bird body size affected detectability. Using larger strip half-width, detection probability was higher for large sized species, intermediate for medium sized species and lower for smaller sized species. Results suggest that for strip half-width larger than 100 m, more attention should be paid to testing assumption of perfect detectability, because abundance estimates may be underestimated when this assumption is violated. Effect of speed of travel of flying seabird on detection probability was also estimated in simulation study, which suggests that detection probability was underestimated with increasing flying speed. |
