Analysis of occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA
October 22, 2024
These data were collected to test whether presence-absence surveys can aid in the identification of nesting sites for the Marbled Murrelet (Brachyramphus marmoratus), a threatened seabird that nests in older-aged forests along the Pacific Coast. The code presented here utilizes four data tables (csv documents) which are formatted according to tidy data principles. Those files are also available at https://doi.org/10.5066/P13DHFQP. The code provided here replicates the analyses in the associated manuscript.

Presence-absence surveys yield spatially imprecise information about nesting sites of an endangered, forest-nesting seabird
Presence-absence surveys are frequently used to monitor populations of rare and elusive species. Such data may also be used as a proxy for breeding activity, but links between presence-absence data and higher-order processes must be validated to determine their reliability. The Marbled Murrelet (Brachyramphus marmoratus) is a threatened seabird that nests in older-aged forests along the...
