North Seymour hosts one of the world's largest colonies of magnificent frigatebirds — males inflating their extraordinary scarlet gular pouches to drum-beating displays just metres from the trail. A specialist ornithologist-led small-group walk turns this into a once-in-a-lifetime behavioural study.
What to expect
Both the magnificent frigatebird (Fregata magnificens) and great frigatebird (Fregata minor) nest simultaneously on North Seymour — a rarity worldwide — and your naturalist guide explains the subtle differences in courtship tactics and territorial behaviour between the two species in real time. The trail also skirts dense sea lion nursery beaches where pups spar in the surf, and land iguana burrows dot the path. The guide keeps pace slow and deliberate, pausing whenever animals display or interact. Post-trail, the vessel anchors for snorkeling in the channel between Seymour and Baltra.
Good to know
Breeding season peaks June to November for frigatebirds — this is when males are most likely to be displaying. Even outside peak season, nesting activity is visible year-round. Maintain the mandatory 2-metre distance from all wildlife at all times; your guide will remind you. Comfortable walking sandals or trainers are sufficient — the terrain is flat volcanic rock.
