Although there was a weather heat advisory in effect, the conditions did not feel as bad as forecast ( 90°F ) and the Audubon Society & park provided free bottles of water to the attendees which was much appreciated.
The photographs were taken with a Canon RF 24mm-240mm lens. It's my favorite all-around lens but not especially exceptional for pure bird photography when higher resolutions are the norm but is better for subjects like butterflies, in my opinion.
