So I stepped outside day before yesterday and one of the parents started swooping at me. She/he only does that when the chicks are ready to fly. It is at that time when they are most vulnerable.
So, I take a picture of the nest and the one that is giving me the stink eye, as if to say enough with the paparazzi, takes off.
She/he hops around on the ground with a parent in close proximity and slowly gets higher and higher off the ground. Without a tail, at this time, she/he is a tad wobbly.
