Freeman Seabird Preserve

Freeman Seabird Preserve FSP is the last Wedge-tailed Shearwater colony on the south shore of O'ahu. Hawaii Audubon Society is the steward of this land.

Approximately 800 birds nest in this restored breeding site, surrounded by native plants. Following the donation of a one-acre coastal plot in 2007, the Hawaii Audubon Society established the Freeman Seabird Preserve at Black Point. Ongoing habitat restoration and colony monitoring work seeks to increase our knowledge of the shearwaters and all that they encompass.

Wedgies are back, prospecting and finding their mates, and checking out the artificial nests.

Wedgies at the Freeman Seabird Preserve are home to a diverse community of ectoparasites... supporting feather lice biodiversity.

HPU graduate students Mikinley Weaver and Sydney Brown quantified ectoparasites in Wedge-tailed Shearwaters by sampling 241 O'ahu birds between 2015 and 2023. This study revealed a consistent lice assemblage, with changing diversity and overall abundance in chicks, fledglings, adults. Read more here: linkinghub.elsevier.com/retrieve/pii/S1383576925001151

The chicks are almost done growing their flight feathers. The length of the outer-most primary (P10) and the wing chord are almost perfectly correlated (r = 0.96). The first chicks fledged this week, and we expect all of them to leave the colony in the next two to four weeks.

The chicks continued growing their flight feathers. The length of the outer-most primary (P10) and the wing chord of the chicks are almost perfectly correlated (r = 0.99).

The chicks started growing their flight feathers and this week we measured the outer-most primary (P10) of 10 of the 40 monitoring chicks. The length (chord) of the wing increases at a faster rate, once the P10 starts to grow and the wings develop.

Thank you to the volunteers who came out for the colony census on September 14th.

The chicks continue to grow and the older ones are reaching 250 grams. They are still covered in down, and the first wing feathers will start growing by the middle of September.
