After about 8 seconds, squeaky calls are heard, and again after 17. I have been hearing these calls from the top of the buildings for the past week, mostly after sunset, combined with repetitive call that remotely remind of pygmy owls or thick-knees. They are only heard intermittently and the traffic noise makes it impossible to get a good recording. I have been watching out for any perched or flying bird around, but I have not seen any that could possibly be responsible for these sounds. The calls do not fit with the usual suspects of the area, but it makes me think of a large raptor with nestlings.
