LIDICKER 1990 June 30 cont. to village of Poltuk . Then we crossed to E side of Narew River & then continued N another 10 km. to a small village near the river - Szygotowek . This is where Aleksander Wasilewski (Olek) & Maria Mazurkiewicz (Vika) have a weekend cottage. Because the map this Olek had drawn for me was not good, we went ~15 km further NE to Obryte before turning back & eventually finding them. I drove the Polish first from Poltute on. Visited, heard for a long excursion ( Olek is ornithologist) making way at the River -~ 1 km from boat when tremendous wind, rain, + hail storm broke out & we were absolutely covered by the drive we got back to the land. Atx, talked. I looked some more after the storm: beautiful! Left ~ 20:00 & drove as back home to Warszawa - lots of mud & deep puddles to maneuver through before reaching fravament. Stopped for about 1 min. near Zegrze near where the Bug + Narew rivers join. Birds seen today: Gray Heron - 55+ including a nesting colony & at least 20 nests mostly with newly fledged young. White Stork - 7+ incl. 3 or 4 nests, 1 with half grown up. Black Stork - Olek showed us a nest that has been used for at least 20 yrs. but was abandoned this year when hunters built a small wooden tower ~ 150 m. from the nest. Mallard - 30+ (Zegrze) Ferrugineous Duck - 1 (Zy.) Tufted Duck - 1+ (Zy.) Buzzard - 1 BIK. K: A - 2
