Nearly spherical eggs like owls, pointy cone eggs of shorebirds like the common murre, even the tiny tic-tac eggs of hummingbirds...and everything in between.
The common murre or common guillemot (Uria aalge) is a large auk. It is also known as the thin-billed murre in North America. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North-Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.
