2016 Seabird Survey

By Tubbataha Management Office Published on May 16, 2016 5:16 pm

Seabirds spend their entire life in the open ocean, using pelagic islands and islets as breeding sites and for raising their young.  Although they have longer life spans, seabirds breed much slower and have fewer chicks than other birds.  They are biological indicators of the health of the ocean.

The Tubbataha Management Office monitors seabird populations monthly and quarterly using various methods.  An annual survey on the second week of May each year combines all survey methods to come up with a more accurate estimate of numbers.  This year the survey was conducted from 9 to 14 May 2016.   Here is what happened those four days…

Absent since 1995, a lone masked booby (Sula dactylatra), believed to be male, made a surprise appearance early morning of 11 May at the Bird Islet. It is uncertain whether it will stay in the Islet or fly away once again. Photo by: Godfrey Jakosalem

It was a great effort to get the 2016 seabird research team together for a family picture as everyone had assignments to finish. When finally, a photo could be taken, an esteemed member of the team, ornithologist Dr. JC Gonzales, was nowhere to be found. Hence a second photo, below, had to be taken. Photo by: Godfrey Jakosalem

The once lush trees in the South Islet have mostly died due to overfertilization with guano from bird droppings. Nevertheless, almost 11,000 seabirds were found nesting in the islet. Volunteer ornithologist Lisa Paguntalan count black noddies, their nests, and chicks. Photo by: Retchie Pagliawan

When just five years ago this area in the South Islet was canopied, now it is exposed the sun. Some trees have fallen. Devoid of nesting materials, black noddies (Anous minutus worcestrii) are experiencing a shortage of materials with which to build their nests. Photo by: Amado Bajarias, Jr.
