By "birds" I assume you mean modern birds (Neornithes); ancient birds
like Archaeopteryx have been around since the late Jurassic.

This site has a reconstruction of the early penguin along with a
phylogeny diagram: http://scienceblogs.com/pharyngula/2006/03/waimanu.php

The diagram includes Vegavis, an early Anseriformes (waterfowl) from
known from a partial fossil from Antarctica, which is placed before
the K/T boundary.  http://www.digimorph.org/specimens/Vegavis_iaai/

(The DigiMorph website, http://www.digimorph.org, is well worth a
look - spectacular 3D images of biological specimens, modern and
fossil.)
