In May, Bob Mulvihill, Arboretum Board Member and employee of the National Aviary, gave a series of bird walks in the arboretum on weekend mornings.

People of all ages attended these informative and educational walks in the arboretum. One of the highlights was the nesting efforts of two Blue Birds in a box placed in the meadow; but, unfortunately, none of the young ones survived. A pair of Goldfinches also surprised birders with their initiation of nest building efforts in May when they usually build their nests in the summer.

The Veteran's Tree Shingle Oak tree was decorated for Memorial Day, May 2013 with 50 small flags, donated by Eileen Bourgeois, Arboretum Board Secretary. The Shingle Oak, donated by the Lion's club, survived the winter in good condition. It was dedicated in May of 2012 with Lion's Club members, Veterans, Board members, and Congressman, Tim Murphy in attendance.

A Royal Paulowania tree, donated by Greg Smith, was planted along the right meadow pathway. This tree is known for its extra big leaves and aromatic flowers.
Boy Scout troop 562 planted 12 small native Persimmon Trees, donated by the Pennsylvania Game Commission, along the left side of the meadow with the assistance of Board Member, Pam Ferkett.

Norma Wright, Board member, supervised the planting of a variety of fern species in the triangle fern garden leading into the arboretum.
