Stacked data format for occupancy modelling

[taylorheadland]

Hi there,

I've been following along with the eBird best practices workbook using the occupancy modelling section as help for a PhD chapter that I am completing using eBird data. Essentially I am trying to assess the impact of urbanisation on raptors across Australia using occupancy modelling and pland_13_urban as my only site-level covariate. I am using multiple years of data, however, I would like to stack these years into a single season model like the one laid out in the best practices workbook. An example of the stacked data can be laid out here (https://kenkellner.com/blog/ubms-vignette.html#3_Example:_%E2%80%9CStacked%E2%80%9D_model_with_random_effect), which is treating site-year combinations as sites. I then plan to account for the pseudo-replication by having site as a random effect using the ubms package, which behaves like the unmarked package.

Is this something that is achievable with the eBird data?

Thanks,

Taylor
