Data frames for 2 species from the breeding bird survey (BBS). Each
 data frame has a row for each site and columns for each sampling
 event. There is a point count and occurrence--designated by
 <code>.bin</code>-- version for each species.

datasets

Fits hierarchical models of animal abundance and occurrence to data collected using survey methods such as point counts, site occupancy sampling, distance sampling, removal sampling, and double observer sampling. Parameters governing the state and observation processes can be modeled as functions of covariates. References: Kellner et al.
