Kermadec Petrel

Pterodroma neglecta

A defiant day-flyer in a family of nocturnal wanderers, the Kermadec Petrel is a spectacular sight over the Pacific waves. With its striking white wing flashes and incredible color variety, it remains one of the most enigmatic seabirds for coastal observers.

Behavior

The Kermadec Petrel is a master of the air, utilizing dynamic soaring to traverse vast distances across the Pacific Ocean. Unlike many of its 'gadfly petrel' relatives that only visit land under the cover of darkness to avoid predators, this species is famously diurnal. At their breeding colonies, they can be seen soaring in large numbers during the day, performing impressive aerial displays over cliffs and slopes.

They are generally solitary when at sea, but they become quite social during the breeding season. Interestingly, they are surface-nesters, which is unusual for petrels. Instead of digging deep burrows, they often lay their eggs in simple scrapes on the ground or under the shelter of low-hanging vegetation and rocky overhangs.

Camera Tips

Since Kermadec Petrels are surface-nesters rather than burrow-dwellers, camera placement is much easier than with other seabirds. If you are in a coastal or island environment where they breed, place your camera on a low-profile ground stake or a weighted base near rocky outcrops or the edges of scrubby vegetation. Position the lens about 12 to 18 inches off the ground, angled slightly upward to capture both their ground interactions and their frequent take-offs.

Because these birds are active during the day, you can prioritize high-resolution color settings over infrared. Use a fast trigger speed—ideally under 0.25 seconds—to catch their rapid movements. If your camera features a 'Pro-Capture' or 'Pre-trigger' mode, enable it; these birds often drop into their nesting sites with very little warning, and you’ll want to see the moment of landing.

Salt spray is the biggest challenge for capturing this species. Use a weather-sealed camera housing and apply a hydrophobic coating (like a specialized lens wipe) to the outer glass to prevent salt crusting from blurring your shots. If you are setting up for a long-term study, a small solar panel accessory is recommended, as the constant activity at a diurnal colony can drain batteries quickly through frequent triggers.

Similar Species

Species that look similar or are commonly confused with Kermadec Petrel.

Herald Petrel

Very similar in appearance but lacks the white shafts on the primary feathers found in the Kermadec Petrel.

Trindade Petrel

Found primarily in the Atlantic; has a different wing shape and generally lacks the diagnostic white primary shafts of the Kermadec.

Soft-plumaged Petrel

Smaller with a distinct dark 'hood' and chest band, and strictly nocturnal at breeding sites.

Frequently Asked Questions

Unlike most other petrels, Kermadec Petrels are strongly diurnal at their breeding colonies, meaning they are most active during the middle of the day and can be seen flying over land in bright sunlight.

Kermadec Petrels are strictly pelagic birds and cannot be attracted to traditional backyards. They only come to land on specific remote islands to breed and do not visit bird feeders.

Their diet consists mainly of squid, small fish, and marine invertebrates which they pluck from the surface of the ocean while flying or floating.

No, they are never found in suburban areas. They spend their entire lives at sea, only visiting remote, uninhabited or sparsely populated islands for nesting.

The best way to distinguish them is by looking at the primary feather shafts; Kermadec Petrels have white shafts on their wing feathers, whereas Herald Petrels have dark shafts.
