What do bees, hummingbirds, white-winged doves, and tarantula hawks have in common? They are all pollinators! While feasting on nutritious nectar, berries and seeds, these hard-working animals help pollinate desert plants like ironwood, saguaro and the night-blooming cereus, which would not be able to produce seeds otherwise. Pollinators are critical to ensuring the health of plants and animals, including humans!
