Thanks! This tree has different coloured blooms from the usual Flamboyant trees seen around the area. They tend to be 'redder'. In fact. I even posted a photo to try, elsewhere, to find if this was a different variety.
Only the Cinnamon hummer is using it.
Only the Plain capped are using the Erythrina poeppigiana
And only the female Canivets emerald is using the Russelia equisetiformis.
