Image 3 shows the presence of a 2nd native bee (Exoneura sp ?). It seemed more interested in the base of a flower whereas the other bee was focused on the pollen.
This bee is still perched on the pollen presenter. The nectaries are at the base of the floret see picture in "Name that Flower' by the Lees. The flowers are adapted to bird pollination.
Thanks, Roger. Very interesting about the bird/flower setup. I'll check out the picture. I have noticed that European honeybees tend to push their way into the base of the flower.
