Girl is a child. Woman is an adult. Young woman if it's vaguely in between.
Female if you're doing medicine or science.
The girl lost her doll. The woman paid her taxes. The young women got dropped off at the movies. The female puffin lays one egg per season and shares the burden of caring for the puffling equally with their mate.
They are! And it's one of the nice things to know in times like this.
There's a town in eastern Canada where sometimes pufflings get lost on their inaugural flight. The entire town goes out during the season to round them up, take them to a rehab facility to make sure they aren't hurt.
In the morning, the families take the healthy pufflings to a cliff and hurl them into the sea.
This sounds awful until you recall that puffins are aquatic birds who live on cliffs, so it's really just the first step towards breakfast for them.
