On 23th April I visited a Marsh harrier breeding site. Two older adult and a first adult male and two females used the approximately 5.5 ha area.
They were all busy but I did not observe any aggressive behaviour during my 3-hour staying; the males rarely performed display flights in spite of the excellent weather.
One of the adult females was actively building her nest.
I upload additional photos to New images gallery.
Best regards, Andras
