There’s the guzzler, (male, red neck)…..drinks for at least 5 - 6 seconds straight and does it at least 8 times, then there’s bobber, she (no red neck) bobs up and down drinking for about 10 times, then there’s “Ms perfect”, (no red neck), drinks for at least a couple of seconds, then pimps, fluffs her feathers, scratches, and then drinks again, last and #4 hummer is a male, (red neck) that just comes, drinks a few sips, and really just waits for the others to come so he can shew them away. I absolutely love my hummers.
