Split confined birds at OOST_VOC in two deployments #157

5 LBBG_JUVENILE birds have release_location VOC_OOST, but their track session start is earlier than their actual release date. Likely to also have records for the movements at VOC?

tag id track_session_start_date release date
193965 2020-07-24 18:00:00 2020-09-11
193968 2020-09-04 18:00:00 2020-09-11
193973 2020-07-24 18:00:00 2020-09-11
193985 2020-07-24 18:00:00 2020-09-11

I think it would be better to split those into two deployments, e.g.:

tag id track_session_start_date release date manipulation type
193965 2020-07-24 18:00:00 2020-09-11 confined
193965 2020-09-11 - ?

@EricStienen:

confined = The animal's movement was restricted to within a defined area
none = The animal received no treatment other than the tag attachment
relocated = The animal was released from a site other than the one at which it was captured
manipulated other = The animal was manipulated in some other way, such as a physiological manipulation

All 5 trackers were first used on juvenile birds in Zeebrugge, that where however predated by a fox soon after fledging. Next these trackers were deployed to juvenile that where experimentally raised in the VOC. Release date 11-09-2021 should therefore be the start date of the new individuals. However , the data of the individuals that were initially equiped with the loggers should not be lost as it might give important information on their postfleding behaviour (although short). Could you split the data into é differnt parts?

Metadata are now split into two deployments (in Ornitela metadata spreadsheet): one for juvenile (found dead) and one for reuse on bird raised in VOC. For the second bird, deployment starts after release from VOC. Since the bird was not confined, but otherwise still manipulated, the type is set to manipulated other in 71d677e
