This week we ponder questions like How do weavers and pygmy falcons have a symbiotic relationship? What does it mean for egg-hatching to be asynchronous? Which back-to-school supply is closest in size to this bird? and Why does this little guy have so much riz?

Happy National Zookeeper Week to all of our hard-working animal-loving babes out there - we see you and <3 you. Stay grimy!
