Our invites looked like that... super easy IDs (think roseate spoonbill), and the questions were things you might learn in biology, like what class a bird was in, or if they were oviparous or viviparous
wat is oviparous or viviparous??? :oops: :oops: :oops: im not that great....please tell because if i learn this, one less thing to search for... :D thanks!

1. Go to google.com
2. Type "define:oviparous"
3. Hit enter.

Oviparous is reproduction via eggs (eg. birds)
Viviparous is where the embryo develops in the mother (live birth)

Yeah, Oviparious would mean birth by eggs. There is a third type, called ovivivparous, where the eggs hatch in a mother and the babies come out live, but that doesn't apply to birds. It was a bad question because it was supposed to be about the specific bird, which doesn't make much sense if all bird are the same in that aspect, and are also all in the class Aves.

*ovoviviparous
Yeah, don't take that test for a good example of, well...a test. I already explained what happened there once.

whoops, confusing typo...


Do you know who held Ornitho at CLC last year? That was a really good test, with models for most stations, except that it used a lot of off list birds

Nah, sorry, not offhand. It was a good test (I have it stashed away someplace), but using specimens not on the Official List is more of a crime than writing a test too easy for even Div. B, if you ask me.

He asked a serious question and you had to...okay, that was funny :lol:, but...
Let's clear this up. Oviparous species lay eggs. All birds lay eggs, so all birds are oviparous; you can put oviparity down as one of the Class's defining traits becuase you get questions like that occasionally. Other than birds (now this is more than you wanted to know), I think, for example, all reptiles are oviparous as well as monotremes. Viviparous species are placental mammals, us. They have live birth. Ovoviviparous species have eggs but the mother does not lay them and instead carries them around somethingorother. Look it up if you want more examples.
The so-what here is now if you get this word, you can break it apart and remember what it means because the prefix means egg (right?).
