Red and Wilma... and Pebbles?

The first bird to show up on our patio two years ago was a house finch. Since then, a few house finches have made our tree their home and our bird feeder their kitchen. Because of the red color of the male, we named him Red. I would occasionally refer to the female as Wilma, attempting a punny reference to the Flintstones.

A few days ago, I was home during the day and heard excessive cheeping at the feeder. I could tell it was a finch, but it sounded odd. I peeked between the blinds to find three finches munching on lunch... Red, Wilma, and a fuzzy-headed addition. I think Pebbles is an appropriate name.

Here she is eating at the feeder next to Wilma. Although she's eating some on her own, she's still being fed some by her parents, too, as the next picture shows.
