Both these birds are so prehistoric looking and only seems like a bird to me because they fly. They are so unusual looking that it is always a thrill to see either.
There are only 2 types of Cranes in North America, the Sandhill and the Whooping Crane (these are rare indeed). They belong to the family
Gruidae. 10,000 million year old fossils related to the Cranes have been found so they could have been flying around with the dinosaurs. They have a 7ft. wingspan. All I know is that the Cranes at Kensington are friendly birds for the most part as long as you are not getting too close to their young. They make a very harsh honking ....check it out by clicking in the link below.

The Heron (this is a great Blue) is from the family
Ardrielae and there are several species such as the Green, Tricolored, Black-crowned Night heron, Yellow-crowned Night Heron, Little Blue plus more. Egrets and Bitterns are in the same family and there are more sub-species of these. All these birds are waders and again, seeing them fly is amazing.
