Blue-tailed Bee-eater (Merops philippinu) by alabang, on Flickr

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Black-crowned Night Heron (Nycticorax nycticorax) by alabang, on Flickr

Despite being fairly ubiquitous on a global level, the slightly unusual nocturnal habit of the black-crowned night heron renders it less conspicuous than most other herons (2) (3) (4). Of moderate size for a heron, this stockily built species has short legs and a short neck, with the male, on average, being the slightly larger of the sexes (2) (5). As its name suggests, the adult black-crowned night heron has a glossy, black cap that extends down the upper back, while the rest of the body plumage generally ranges from white to ashy grey (2) (5). The nape is adorned with two to three long, white plumes reaching up to 25 cm in the breeding season (5). The stout bill is black in colour, the eyes, a piercing crimson, and the legs, yellow-green for most of the year but becoming pink during the breeding season (2) (5). Juveniles are mostly brown, with heavy striping and pale spots, but as they grow towards the adult plumage, become more solidly dark above and pale below (2). Four subspecies that differ subtly in appearance and occupy different ranges are currently recognised: Nycticorax nycticorax nycticorax, N. n. hoactli, N. n. obscurus and N. n. falkandicus (2) (5).(5)[/URL][/SUP].

Thank you April.


Long-tailed Shrike (Lanius schach) by alabang, on Flickr

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Brown Shrike (Lanius cristatus) by alabang, on Flickr

This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch. The use of multiple measurements allows discrimination of the sex of about 90% of the birds Subspecies lucionensis has a grey crown shading into the brown upperparts and the rump appears more rufous than the rest of the upperback. The tail is more brownish and not as reddish as in the Red-backed Shrike. Younger birds of lucionensis have brown crown and lacks the grey on the head. Supspecies superciliosus has a broad white supercilium and richer reddish crown. The tail is redder and tipped in white.

Chestnut Munia, (Lonchura atricapilla) by alabang, on Flickr

he Chestnut Munia, (Lonchura atricapilla) (formerly considered as a  subspecies of the Tricoloured Munia Lonchura malacca atricapilla) also  known as Black-headed Munia, is a small passerine bird. This estrildid  finch is a resident breeding bird in Bangladesh, Brunei, Cambodia,  China, India, Indonesia, Laos, Malaysia, Burma, Nepal, Philippines,  Singapore, Taiwan, Thailand, Vietnam and Hawaii. Known as mayang pula  ("red maya", to distinguish it from the predominantly brownish Tree  Sparrow which is also called maya) in the Philippines, perhaps because  of its brick red patch on the lower back that shows only when it flies.  The Black-headed Munia is the former national bird of the Philippines  (the Philippine national bird is now the Philippine eagle).

It makes little sense. I'm amazed this got a cr2. It should be replaced in 2018 or later.

There are more higher volume lenses they need to update than thee two.

Unless they cut the weight by at least 25% I see little reason to upgrade.

Little Egret (Egretta garzetta) by alabang, on Flickr

The little egret is an opportunistic hunter (5), feeding mainly during the day whilst walking through shallow, open water, stabbing prey with its bill (5) (6). It is highly dependent on visual cues when hunting and therefore its feeding is highly affected if the water is not clear (5) (6). It feeds primarily on small fish, which are usually around 1.2 to 6 centimetres in length, but bivalves, crustaceans, and other invertebrates are also consumed (5).

Little egrets breed at different times of the year depending on location. Those populations based in Europe and Asia breed during spring and summer, whilst the breeding seasons of more tropical populations coincide with rainy seasons (5). Little egrets nest in mixed or single species colonies, and lay four to six eggs in single clutch, with the chicks hatching three weeks later and fledging at four weeks old. The chicks will spend a further month in their parents' care before leaving the nest and dispersing (7).

GM5561T if you want the most compact and light weight monopod that has the highest load capacity.
Cool!  I have the 1.4X III and have to say my 400 seems as sharp with it as it does without.

Are you going to use a monopod or tripod?  For sideline sports like football you generally can't use a tripod.  Players could be injured by it.  A monopod is far less dangerous.

I would only use a monopod for sports. A tripod is fine for portraits or landscapes, where your subjects do not move, but for sports - when space is also often limited due to the number of other media - then a monopod is the only option.

+1

Monopod is your only option really - a nice carbon fibre one will be light and strong.

EOS Bodies - For Stills / Re: Difference between US/Japanese 7D?
« on: March 07, 2013, 09:02:27 PM »
That is also the impression I get from other owners. They think the units sold in Japan are superior to those exported. This belief probably stems from the higher Japanese Domestic Market retail price.

Great Egret (Ardea alba) by alabang, on Flickr

With its long, white breeding plumes, orange-yellow bill, and green facial skin, the Great Egret at the height of the breeding season is stunning to behold. Even at other times of the year, when it loses its plumes and its face and bill return to their typical dull yellow, this large, white wader is difficult to overlook. Male and female Great Egrets are similar (38 inches) at all times of the year. The Great Egret is widely distributed across warmer parts of the globe. In North America, the Great Egret breeds primarily in the southeastern United States, with smaller pockets of breeding territory in the Great Plains, the northeast, and in the west. Most of the Great Egrets in the southeast are permanent residents, but those in cooler climates migrate south for the winter, where they may be found along the coast of California, in the southwest, and in Texas. This species also breeds in Eurasia from southern Europe east to east Asia, wintering in North Africa, India, and Southeast Asia. Populations also exist in South America, Australia and New Zealand. Great Egrets live in and around small bodies of water. In summer, Great Egrets nest in colonies, called ‘rookeries,’ in trees surrounding lakes and ponds. This species utilizes similar habitats during the winter. Great Egrets mainly eat fish, but may also take crustaceans and small vertebrates (such as frogs, lizards, and mice) when the opportunity arises. Great Egrets may be best observed wading in shallow water, where they may be seen plunging their bills into the water to catch fish. It is also possible to see Great Egrets at their rookeries, especially when they return to roost at sunset, or while flying with their feet extended and their necks pulled in. Great Egrets are primarily active during the day.

Philippine Duck (Anas luzonica) by alabang, on Flickr

Anas luzonica is endemic to the Philippines, being recorded from all the major islands and eight smaller islands. Records since 1980 derive from c.30 localities, most on Luzon and Mindanao. Records from Siquijor and the Sulus remain unsubstantiated. A steep population decline was evident by the mid-1970s, with high numbers recorded at only a few sites in the following decade, e.g. Candaba Marsh (Luzon) which probably supported many thousands in the early 1980s. Subsequent local extinctions and near-disappearances have occurred in several significant sites, including Candaba Marsh and Buguey wetlands (where several thousand were recorded in 1983). Important current areas include Polillo Island (240 seen and an estimated 3,000 present in 1996), Subic Bay (600 seen in 1997), Magat dam (2,000 were seen in 2001) and Malasi lakes (1,320 were recorded in 2002), Luzon. Other recent records come from Mangatarem, Pangasinan (east of Zambales Mountains IBA) where 70 individuals were counted on the Barabac River inside the Manleluag Spring National Park, Cantilan mangroves in Surigao del Sur and from a mangrove fishpond in Bicol Region, Southern Luzon (B. Tabaranza in litt. 2007). In 1993, its population was estimated at 10,000-100,000, but by 2002 fewer than 10,000 birds were thought to remain.

Sports / 7th Odyssey Waves National Surfing Competition
« on: February 28, 2013, 11:29:52 AM »
The first time I photographed surfing was back in 2007 at the 4th Odyssey Waves National Surfing Competition. Photos of which can be found at the following links

http://paolo1701.multiply.com/photos/album/48/ABCD_Beach_Calicoan_Island

http://paolo1701.multiply.com/photos/album/49/Surfing_Day_Zero

Fast forward to the 7th Odyssey Waves National Surfing Competition that was held last week at Guiuan, Eastern Samar from October 6-9, 2011.

For those unfamiliar where Guiuan, Eastern Samar is located click http://g.co/maps/6be3s The nearest major commercial airport is located in Tacloban City on Leyte Island. Travel distance from the airport to the surf site is 175km of which 170km is paved concrete roads. Guiuan has its own airport that would cut down road travel to 20km.

I have yet to visit other surf sites but the highlights of this place are the beautiful rock formation to the north, sandy white beaches and very few people living on the beach. Making this your private surf site.
