The male red all over with a black face is classic. The female doesn’t have much of a black face, LOL! But I claim no expertise!
I am a learner and delighted to see that you entice them with a bird feeder.
One unique benefit of these birds is that when bitten by mosquitoes with West Nile Fever, the virus cycle seems to be overcome by the birds immunity. That means that this species is relatively no increased reservoir threat around humans and horses when the mosquitoes borne virus transmission is on the news!
