Norfolk Island: The Seabirds

Seabirds were an ever present feature during our week-long stay on Norfolk Island. The star attractions during this trip were small numbers of Black-winged Petrels (above and images below) seen from the island’s north-western cliffs (first image below). They were about during the day, especially when the wind was up, flying along exposed cliff faces and grassy hillsides; the birds nest in small numbers here.
One bird was seen to land (below) before scurrying under a rock overhang, where presumably it was tending a chick.
I saw a well-advanced chick during the day (below). It was evidently being fed by parents returning at night. Why some birds appear to attend to young during the day and others at night is unknown.
I found the headless carcasses of three Black-winged Petrels together (below) at the Captain Cook Lookout in Norfolk Island National Park. The species once bred commonly on the island but was decimated by introduced rats and cats. It is making a minor comeback of sorts, but cats especially continue to be a problem. Nankeen Kestrels, self-introduced to the island, have also been recorded decapitating Black-winged Petrels.
I noticed a big difference in seabird numbers from my last visit to the island in 2007. Masked Booby (adults and juvenile below) for instance, was breeding commonly both on the main island and on offshore islands and rock stacks. It was nesting but in much smaller numbers in 2007.
Similarly, Red-tailed Tropicbird was numerous all about the island, and nesting in several places (adults and juvenile below); I recall seeing far fewer birds in 2007.
Frigatebirds were once scarce on the island but with growing populations of other seabirds, their numbers are on the rise. I saw about 80 together at Captain Cook Lookout and scattered birds elsewhere. Most appeared to be Great Frigatebird (below) but several Lesser Frigatebirds were seen.
Other seabirds were in similar numbers on this trip and in 2007. The delightful White Tern (below) was everywhere, nesting in the magnificent Norfolk Island Pines. Although at the tail end of the breeding season, plenty of well-advanced chicks were being fed on their nests.
Many chicks are blown from the frail nests and fall to the ground, like the youngster below. Unfortunately, large numbers die as a consequence.
Black Noddy (below) is also abundant but relatively few nests in the pines with well-fledged chicks were being attended.
Brown Noddy (below) was much less common and mostly on offshore stacks. About 80 distant Grey Ternlets were also on rock stacks off the north shore. A few Wedge-tailed Shearwaters were seen offshore but their nesting season appears to be over. I had hoped to get to Phillip Island to look for White-necked Petrel and a few other seabirds but rough weather prevented a trip.

Norfolk Island: The Land Birds

We had a pleasant week-long stay on Norfolk Island, our first “overseas” escape since the Covid 19 upheaval began in March 2020. We stayed at the pleasant Saints Apartments and had a hire car to get ourselves around this beautiful island, which I had visited previously, in 2007. Some scenic images below.
A highlight was finding a Norfok Island Boobook, or Morepork (first image). This endemic subspecies of the New Zealand Morepork had been reduced to a single female when two male New Zealand birds were introduced in 1987, in the hope of salvaging the taxa. Today an estimated 30-40 owls reside on the island. I first looked for them on the road to Mt Pitt and heard 4-5, some quite close to the road. However, the road’s steep banks made conditions difficult. I eventually tracked one down in forest near the Palm Glen picnic ground (below).
As usual, the endemic specialties were easy to find. Norfolk Island Parakeet (below) was seen near the summit of Mt Pitt and around Captain Cook Lookout in Norfolk Island National Park, as well as in the Botanic Gardens. Numbers appear to be stable these days after a precipitous decline it times past.
The Slender-billed White-eye (below) was in good numbers throughout forested parts of the island, although being outnumbered generally by Australia’s self-introduced Silvereye.
The recently split Norfolk Robin (below, pair and male alone) was similarly co-operative, being particularly easy to see on and around the summit of Mt Pitt.
Another endemic, the Norfolk Gerygone (below) was abundant in forest and gardens all over the island.
A good candidate for a split is the endemic anthoprocta subspecies of the Golden Whistler (below) which sounds nothing like the species in Australia and is unusual in not having brightly plumaged males.
Similarly, the endemic pelzelni race of the Grey Fantail (above) and norfolkensis subspecies of the Sacred Kingfisher (below) were ubiquitous.
Introduced birds are a feature of the island and there are no shortages of Red Junglefowl, Feral Goose, Song Thrush, House Sparrow, European Starling and others, although the quaint California Quail (below) is suitably agreeable.
