Inca Tern

With a population of 150,000 and decreasing, the Inca Tern is considered a threatened species. Large die offs occur during major El Nino events, which hadn't yet happened as of this spotting. Fishnig and guano harvesting has also decreased this species from its former healthy population in the millions This colony was not at the nearby islands in the district of Callao, as the guide said, but rather hanging out on a pier which housed La Rosa nautica and a handful of gift shops
