Just Outside My Window

A family of birds has decided to live in a vent right outside my Juliet balcony.  I can hear them chirping all day long and sometimes they land on the balcony railing.  I've named them Hank and Hannah, but am ashamed to say sometimes I get them confused.  I left out some bread crumbs for them to eat, but I don't think they like them.  I will have to get some bird seed.  I love having them there; they chirp so beautifully.
