Great Tit nest in a streetlight

As I was walking home just few blocks away from my flat I spotted a bird that flew out from the hole in a pole of the streetlight. At Americké námestie square, almost in the city center I found nesthole of Great Tit (Parus major). Another example how these cavity nestlers accomodate in urban areas.

Urban Blackbird

This Blackbird pair is truly urban breeder. I found its nest 3 years in a row in the same section of Poštová street in the centre of Bratislava. In 2011 in letter "C", in 2012 40m away on the other side of street on the top of small electronic box and in 2013 in letter "E". The meaning of the sign is "Paper store".

Note: I reviewed some older observations of my friend and colleague Ján Dobšovič and I found out, that in 2010 Blackbird was breeding in letter "E" too. Link to that sighting.
