Thanks Tara! I knew that the males were territorial but hadn't heard that about the females. The one I got the shots of at the Pentas flowers is a female but I'm not sure about the one perched on the branch; I can't see the ruby-red throat of the male but it could be the position.
It's storming here this afternoon. I don't much care for the thunder and lightning which always startles me ... but I am so thankful for the rain!
