　This year we conducted research in Jurbarkas, the same site as
　in 2015.　During our survey we confirmed 4 individuals with
　geolocators attached but due to being late in breeding season
　these individuals were not nesting.　We typically use bow-nets to
　capture nesting individuals but this time we attempted
　recapture by use of mist-nets.　Though multiple attempts were
　made, we were unsuccessful in retrieval.

Although the task of retrieving geolocators was halted, we were successful in attaching another 4 units as
well as 3 GPS logger devices purchased by donations from our supporters.　We now have 21 little terns
with geolocators and 3 with GPS units for a total of 24 birds released in Lithuania's Nemunas River.　In order
to insure success for next year, we must think of alternative recapture methods.

Jurbarkas is an important area for the breeding of little terns. Fisherman and other river visitors often
enter nesting sites unknowingly.　Cautionary signs were posted in areas used for nesting to gain the
understanding of local residents.
