Factual error: The Nile crocodile is a bright green color. Nile crocodiles are actually dark olive - brown.
Continuity mistake: When Chris is trying to activate Hummingbird Power, his skin is suddenly lighter than in the previous shot.
To Touch a Hummingbird - S2-E10
Other mistake: Chris gets on the zip line and hooks up. Martin just stands behind him, not hooked up to the zip line. Chris zooms off down the line chasing the hummingbird. A few seconds later, Martin is suddenly on the zip line also and right behind Chris.
Other mistake: When Aviva makes Turkey Power Discs, the Creature Power Suit buttons are looking angular and plain instead of round and convex.
Continuity mistake: When the Tortuga is in the twister Aviva is rolling on the ground, but then she is hanging on a tree branch in the air.
Mystery on the Prarie - S3-E14
Character mistake: If Chris and Martin are creature experts, they would have already known the buffalo birds are nest parasites.
Revealing mistake: When Martin is amazed about the osprey, Chris' hand clips through Martin's sleeve in front of it.
Groundhog Wakeup Call - S2-E25
Continuity mistake: A couple of seconds after Aviva (in Groundhog Power) has made a hole into the Tortuga's floor, in one shot the main screen is suddenly cyan instead of blue.
Suggested correction: The cyan main screen is actually not the case in "Groundhog Wakeup Call", but in another Wild Kratts episode, the error is shown.
Continuity mistake: There are 4 dingos chasing Chris and Martin, then there are 5, then when they're in the tree, there are 6 dingos looking at them.
Bass Class - S1-E11
Character mistake: At the end of the episode, a kid catches a bass which Chris says it is a nice smallmouth, when in fact it is a largemouth bass.
