I have a House Finch couple who built their nest in a hanging fern on my porch. I was able to install a camera over the nest the evening before she started laying eggs. The male was around and very excited during nest building but hasn't been around for a while. She had four eggs and then one day she had two. Then it seems she laid another so there are three. I think she's been trying to incubate them for several days but the male has not been around. She has only briefly left her nest the last two days and I think she goes to find the mate because it seems he follows her back. But he doesn't stay around and I do not see him coming to feed her at all. I'm concerned that he has abandoned her. Another couple is building a nest in one of my other hanging ferns. I do not disturb them and do not use that door to enter my house. Anyone know what may be going on?
