Peter,
You realize I hope, how precious the white sided piercer is to all of us outside of the top of the South American Continent. We’d not have a chance of seeing such a beauty.
I adore that upturned-beak and then the sharp downward piercing tip! But that’s I presume for getting nectar in otherwise deep tubular flowers??
What do they get for protein? Do they peck at insects on the bark or leaves of trees or catch them in flight?
The humming birds get their nectar to fuel their flight to catch insects!
Thanks so much for sharing!
Asher
