The second PT photography contest is accepting entries now through July 15. Please read and follow the rules here and pay particular attention to Rule 12.
Update, July 8: Just to clarify, we give preference to photographs of endangered species, but general entries are welcome as well. If we receive enough endangered species, we will establish a separate category. Entries in the animal, mineral, and vegetable categories are also welcome.
Update, July 15: The deadline for submissions is tonight at 10:00 Mountain Daylight Time. MDT is UTC(GMT) - 6 h.
