I am first time breeder. I have a pair of yellow ring necks, I bought them in December last year. I have put a nesting box. the females goes in and out and lately been spending lot of time inside but every time she goes near male he just ignores her. she tilts her head and makes noises but the male doesn't do anything

however after 7pm overnight both of them stay in box. Can anyone help, I am from Pakistan and I dont know the breeding season or anything.
regards
