Ruby-throated Hummingbird, Male JF95387
When you have the opportunity to watch a hummingbird closely, look at the top of their head. Often you will see a dusting of gold, pollen grains from the flowers they have been visiting. Pollen is deposited as the hummingbird visits a flower. It contains the male gametes.
Then as he moves onto another flower, if it has the female flower part, the Pistil, extended out as this Beebalm (Monarda didyma) does, the pollen will be transferred to the pistil and fertilization will take place.
