Survey of breeding area
With help from Dr. Kurlavičius, our team surveyed the breeding area of
the little tern in Kaunas. We were able to confirm two breeding pairs and
non-breeding individuals for total of 8 birds. A few days prior, we were
told there was one more breeding pair, but due to increase in water level
the visiting sight became flooded.

Locating little tern colonies by boat
By use of boat we observed the little tern breeding sight on Neman River.
Through analysis we located and confirmed two little tern colonies and
one possible breeding pair. There were about 20 individuals in the flock
observed at the research area. We confirmed two common tern colonies, one
of which was next to one little tern colony.

Island's geography and nest location
We surveyed the island where little terns were breeding and studied the
island's geography and nest locations. One nest which once contained two
eggs was reduced to only one. One colony contained one more nest and the
nest contained one egg.

Capture of little terns
We set bownet traps around nests and placed video recorders to capture
footage of little terns in Kaunas.

Observing released little terns
We observed little terns released with geolocators attached in Kaunas.
We researched the breeding area earlier confirmed by boat. The nests on
the island were trampled and disturbed. People of Lithuania are not informed
of the necessity for little tern conservation, therefore eggs and young
are crushed by people working along the river.
On July 3rd, a cooperative agreement contract was signed. For more information
On July 4th, we departed from Lithuania and arrived in Japan on July 5th.
Professor Kurlavičius and Ms. Meškinytė continued to capture and study
the little terns after we returned home.
