Need help with sexing Colorado River toads

[cosyis77]

Looks like 2 males to me, though the second one might be female. Check the thumbs of the front feet - do they have "pads" there? Males have these to hold on to females during breeding.

Both males?

Both males?

Definitely.Those nupital pads are pretty obvious and that is a dead give away.

There you go, both males. Females are almost round in comparison to males, when viewed from above.
