I have an entry for this week with the male purple finch found in my post at: https://peakd.com/hive-106444/@porters/a-beautiful-sublime-sunday-bird-songs-from-the-boreal-forest
Another theme you could have is Pairs with the male and female together.
Fantastic, thank you for your entry and suggestion.
It could be a bit tricky, as I have to find a pair among my photos first, but I love the idea. 🙂
