Top 5 Most Common Birds


      


     Telling birds apart can be confusing. Many of them look alike. A lot of the ones that are often seen in the village are roughly the same size. They also move around a lot and are difficult to observe. They constantly hop from branch to branch and hide within the foliage of the trees. How can a novice birdwatcher tell them apart?

     One way to sort out the confusion is to just choose the top 5 birds that one is most likely to encounter and familiarize yourself with those birds first. Studying and memorizing the features of 5 birds is certainly much easier and less daunting than studying all 60 species found in the village or 500+ species found in the Philippines.

      Birdwatchers use field marks to identify a bird. These are particular features of the bird that the observer looks for to differentiate one species from another. These are details like color of the legs or presence of rings around the eyes. In the early 19th century, British gentlemen who wanted to study birds went out and shot and skinned them so that they could view them in hand. It was not until binoculars and field guides were created could birds be studied without their being shot.

     The 5 species of birds most likely to be seen in the village are the maya or Eurasian Tree Sparrow, the Yellow Vented Bulbul, the Pied Fantail, the Long Tailed Shrike, and the Olive Backed Sunbird.

     The most common backyard resident is the ubiquitous maya or Eurasian Tree Sparrow (Passer montanus). This is the small brown bird with a short black bill that is usually seen in small flocks. It is the bird that usually gets attracted when people set out bird feeders or scatter birdseed or rice on the ground. The field mark to look for is the white patch on its cheek.

     The Yellow-vented Bulbul (Pycnonotus goiavier) or is bigger than a maya . It is olive-brown with a black forehead, and white chest and belly. The field mark to look for is the white eyebrow and yellow undertail feathers.

     The Pied Fantail (Rhipidura javanica) or maria cafra is a black and white bird. Its distinctive features are its long black tail that is edged in white and white eyebrow. It frequently spreads its tail out like a fan, as befits its name. It has white underparts with a black band across its chest.

     The Long-tailed Shrike (Lanius schach) or tarat is a handsome bird with a long, slender tail. It has a black head, chunky bill, and white underparts. It is cinnamon colored on its back and the lower sides of its torso. The black, white, and cinnamon colors, plus its long tail give it its distinctive look.

     The Olive-backed Sunbird (Nectarinia jugularis) is a small bird with an olive green back and yellow underparts. The males have an iridescent metallic blue throat. Its distinctive feature is its long, thin, pointed and downward curving beak.

     A surprising benefit this technique is that after taking the time to study the 5 most common birds, all the other birds will seem to easily fall into place. It’s like the roadmap for recognizing birds has been planted in your brain and it will become easier to see the distinctive features and field marks of all the different birds in the village.

Meet the Olive-Backed Sunbird

     It comes as a surprise to many people that there are no hummingbirds in the Philippines. A lot of people have seen a small, brilliantly colored bird darting in and out of the flowers in their gardens. They assume this is a hummingbird. The bird they’ve seen is actually an Olive Backed Sunbird (Nectarina jugularis).

     Like hummingbirds, Olive-backed Sunbirds feed on nectar and small insects and spiders. They can be found in gardens all over Ayala Alabang. They have a long, thin, pointed beak that curves downwards. This type of downward curving beak is described as “decurved”. When they feed on nectar, they either thrust their entire beak into the center of the flower or they use their sharp beaks to pierce a flower near its base and sip the nectar. They have long, thin, tubular tongues that they use to sip the nectar. Unlike hummingbirds that can hover like tiny helicopters, Olive-backed Sunbirds can only hover for brief spurts. They are very agile and fly quickly from flower to flower. They can also snap up insects while perched on treetops.

      Olive-backed Sunbirds are often found in pairs, especially during breeding season. The male and female are easily told apart because the male is more colorful and showy than the female. The male has a shiny, iridescent, metallic purplish-blue throat and upper breast while the female’s throat and upper breast are yellow. Both male and female have olive colored backs and heads, brown and olive wings, and yellow stomachs. The male Olive-backed Sunbirds found Palawan however are colored bright orange below the chest.

     Sunbirds are known in Pilipino as pipit. There are many kinds of sunbirds and the Olive-backed Sunbird is known as pipit- parang or pipit-puso. They are noisy and active throughout the day. Their call is a loud and persistent “tch-wiiiip” and also an insistent, high-pitched, repeated  “chii-chii-chii-chii-chii”. Often, they will perch on the top of a tree calling out “Tch-wiiiip” loudly.

      At home, I see the Olive-backed Sunbirds from my 2nd floor windows feeding on the pale pink flowers of the Tabebuia trees and the bright orange flowers of the African Tulip trees. One of my neighbors attracted a lot of Olive-backed Sunbirds to her garden by planting a lot of Chinese Hat plants. I have also seen them on hibiscus (gumamela) flowers and Cassia trees. They seem to be attracted to all kinds of nectar-rich flowers. It’s pleasing to find that the plants and flowers that bring shade and beauty to the garden also provide food and shelter to colorful and musical birds like the Olive-backed Sunbird.
