The Philippine serpent eagle, endemic to the Philippines, is a largely sedentary species, normally found in primary and secondary forests, woodlands, and open land with scattered trees. It’s considered relatively small, growing up to 53 centimeters tall, with a wingspan of up to 120 centimeters.
Serpent eagles are mostly brown from above, with a black crown, and gray-brown cheeks and throat. They have white spots on their chests and wings (which have given the species the alternate name of Philippine crested serpent eagle), and their eyes and legs are yellow.
As its name suggests, serpent eagles have been known to feast on serpents and other reptiles, reported Rafael Antonio in a 2015 news article on Inquirer. net. However, they also feed on rodents and small mammals.
While their population has been decreasing, their species has not been declared vulnerable because vulnerable populations need to have had a decline greater than 30 percent over the last ten years or three generations. Each generation for Philippine serpent eagles lasts around 12 years, according to a 2018 online factsheet from Birdlife International.
The Philippine serpent eagle can reportedly be found in most parts of the country, except for Palawan.
