You know it's early spring when the sparrows start building their homes

 

Here they are thinking of where, how and when
 

The next door neighbour has already settled in

 

 

Female on the ground floor

 

Male a few days earlier building the ground floor

 

And now we have an occupant on the second floor!

The penthouse apartment is still unoccupied as of today

 

Here's another nest box on the rear of this building 

(video taken last year, no audio)

Happy Spring!
