zoo lovers day

Each year on April 8, National Zoo Lovers Day is observed.  This would be a perfect day to visit a zoo and be one of the millions of people who visit them each year. Enjoy seeing your favorite animals swinging from the trees or splashing in the water and have a fun-filled day.

Zoo is actually short for Zoological Garden, and is mostly used to refer to the modern concept of a zoo.   Prior to this the term menagerie was used, coming from a long history reaching back all the way to the ancient world.  The oldest collection of this sort was found during an archeological dig in Hierakonpolis Egypt in 2009.   The animals they had there included an impressive array of hippos, elephants, baboons, wildcats, and hartebeests.

The oldest modern styled zoo was established in 1752 at the order of Emperor Francis I, in the beautiful city of Vienna, Austria.   It was intended solely for the viewing pleasure of the imperial family, but was extended to the public in 1765.   The next zoo to open was in 1775 in Madrid, and then another in Paris in 1795.

A few zoo facts:
