My own
observation I have done on the Bulwar Nadmorski
(Seaside Bulwark) in Gdynia and on Patulskie Lake.
Observing birds in city was easy, because ducks, which
were fed by people were domesticate. I thought, that the
observation on the lake was aimless and I stopped them,
because afraid birds were flying away with noise. Ducks
(from the lake) fly away in winter and come back in
March, and that fed (from city) stay here. Cross duck,
taking its food is diving not all time. It often puts
only its head into the water. |
