Pelicans, which have always reminded me of pterosaurs, seem to do this slightly when they launch. Video I took the other week of one: https://serio.com.au/imag

  It's very different actually - the pelican, as every other bird, uses its hind legs to push off, while the pterosaurs (and some bats) push off with their forelegs - and the latter ones are very powerful and can be re-used for flight, unlike the powerful hindlegs of large birds which are just dead weight when they're airborne.
