Roof nesting gulls and terns in Amsterdam







Possibly the first known colony of Black-headed Gulls Chroicocephalus ridibundus on a roof in Amsterdam (Hoofddorppleinbuurt, 5 June 2018). The total number of nests remains unknown as they nest there between solar panels. A best guess... about 10 nests??  (update: turns out they're already nesting 'in good numbers' on roofs in the Westhaven area (annually?) and Amsterdam Zuidoost (2 pairs in 2015, thanks Ruud!).



About three pairs of Common terns Sterna hirundo nest among the Black-headed Gulls.






Herring Gulls Larus argentatus (photo above) and Lesser black-backed Gulls Larus fuscus also nest in the area, but their nests are more widespread and difficult to detect.

Commuting Peregrines









What I see on a daily basis. Unfortunately also one of many things that will forever remind me of someone who recently passed away. Someone who meant an awful lot to me (and to these birds) the past two decades.

New balcony birds





Two White storks Ciconia ciconia inspecting a potential place for their nest... in the heart of Amsterdam (De Pijp, March 30, 2018).
