2-6-2017 MONTE CORONA, VALENCIA - PAINTED LADY BUTTERFLY (Vanessa cardui)
Vanessa cardui is the most widespread of all butterfly species. It is commonly called the painted lady, or formerly in North America the cosmopolitan.
V. cardui is one of the most widespread of all butterflies, found on every continent except Antarctica and South America. In Australia, V. cardui has a limited range around Bunbury, Fremantle, and Rottnest Island. However, its close relative, the Australian painted lady (V. kershawi, sometimes considered a subspecies) ranges over half the continent. Other closely related species are the American painted lady (V. virginiensis) and the West Coast lady (V. annabella).
Larvae feed on Asteraceae species, including Cirsium, Carduus, Centaurea, Arctium, Onopordum, Helianthus, and Artemisia.
The painted lady uses over 300 recorded host plants according to the HOSTS database.
Adult butterflies feed on flower nectar and aphid honeydew.

17-5-2017 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)
%2020.jpg)
Raising a nest full of baby herons is hard work! During the breeding season, some Gray Herons spend up to 23 hours per day foraging and some travel up to 38 km (24 miles) from their nest in search of food.
Gray Herons usually feed on smaller fish, 10–25 cm (4–10 inches) long, but some ambitious individuals take fish weighing up to 500 grams (1.1 pounds) and eels that are up to 60 cm (24 inches) long.
Gray Herons live in Eurasia and Africa, but rare individuals stray from their normal range to places like the Lesser Antilles in the Caribbean Sea. Despite the Gray Heron's similarity to Great Blue Heron, some observers have also documented this species from the Atlantic Coast of mainland North America, from Newfoundland to Virginia, and also from Alaska’s Aleutian Islands.

19-4-2017 MONTE CORONA, VALENCIA - SPECKLED FOOTMAN MOTH (Coscinia cribraria)
%2020.jpg)
Coscinia cribraria, the speckled footman, is a species of moth belonging to the subfamily Arctiinae within the large family Erebidae. This moth has a widespread distribution in the Palearctic.
Coscinia cribraria has a forewing which has a background colour of dirty white marked with black streaks along the wings and crossbands made up of dark dots, both of which vary in extent. The subspecies arenaria has an almost pure white forewing.The speckled footman has a wingspan of between 30 and 35 mm (1.2 and 1.4 in).
Coscinia cribraria has a wide Palearctic distribution being found from Northwestern Africa Iberia and southern Great Britain east to China and Mongolia.[1] In Europe, north of the Alps, the speckled footman is typically found on sandy heaths and open sandy pine forests. To the south of the Alps, it inhabits on dry mountain meadows with stony or rocky areas and around the Mediterranean this species can be found in habitats like maquis and in open forests.

17-4-2016 VILLALONGA RESERVOIR, VALENCIA - COMMON SANDPIPER (Actitis hypoleucos)
%2023.jpg)
The common sandpiper (Actitis hypoleucos ) is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper (A. macularia ), make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus Tringa.
%2024.jpg)
The adult is 18–20 cm (7.1–7.9 in) long with a 32–35 cm (13–14 in) wingspan. It has greyish-brown upperparts, white underparts, short dark-yellowish legs and feet, and a bill with a pale base and dark tip. In winter plumage, they are duller and have more conspicuous barring on the wings, though this is still only visible at close range. Juveniles are more heavily barred above and have buff edges to the wing feathers.
This species is very similar to the slightly larger spotted sandpiper (A. macularia ) in non-breeding plumage. But its darker legs and feet and the crisper wing pattern (visible in flight) tend to give it away, and of course they are only rarely found in the same location.

The common sandpiper breeds across most of temperate and subtropical Europe and Asia, and migrates to Africa, southern Asia and Australia in winter. The eastern edge of its migration route passes by Palau in Micronesia, where hundreds of birds may gather for a stop-over. They depart the Palau region for their breeding quarters around the last week of April to the first week of May.
The common sandpiper forages by sight on the ground or in shallow water, picking up small food items such as insects, crustaceans and other invertebrates; it may even catch insects in flight.
It nests on the ground near freshwater. When threatened, the young may cling to their parent's body to be flown away to safety.

23-3-2017 PANAMA CITY, PANAMA - BLACK THROATED MANGO (Anthracothorax nigricollis)
%2010-gigapixel-scale-1_4x.jpg){kind=tracking}
The black-throated mango (Anthracothorax nigricollis) is a species in subfamily Polytminae of the hummingbird family Trochilidae. It is found in Panama, in every mainland South American country except Chile, and on Trinidad and Tobago.
%2020-gigapixel-scale-1_4x.jpg){kind=tracking}
The nominate subspecies of the black-throated mango is found from western Panama into much of Colombia and Venezuela, the Guianas, eastern Ecuador and Peru, northern and eastern Bolivia, eastern Paraguay, far northern Argentina, most of Brazil, and on both Trinidad and Tobago. It has also occurred as a vagrant in Uruguay. Subspecies A. n. iridescens is found in extreme southwestern Colombia, western Ecuador, and extreme northwestern Peru.
The black-throated mango inhabits a variety of landscapes in the lowland tropics, most of them semi-open to open. These include gallery forest, shade coffee and cacao plantations, the edges of dense forest, and parks and gardens in populated areas. In general it is a bird of the lowlands, but reaches 1,400 m (4,600 ft) in Venezuela, 1,700 m (5,600 ft) in Colombia, and 2,000 m (6,600 ft) in eastern Brazil.

16-4-2021 GREAT SPIRIT BLUFF CAM, MINNESOTA - NORTH AMERICAN PEREGRINE FALCON (Falco peregrinus ssp. anatum)
The peregrine falcon (Falco peregrinus), also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop (high-speed dive), making it the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptorand one of the most widely found bird species. In fact, the only land-based bird species found over a larger geographic area is not always naturally occurring, but one widely introduced by humans, the rock pigeon, which in turn now supports many peregrine populations as a prey species.
The peregrine is a highly successful example of urban wildlife in much of its range, taking advantage of tall buildings as nest sites and an abundance of prey such as pigeons and ducks. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations. Experts recognize 17 to 19 subspecies, which vary in appearance and range; disagreement exists over whether the distinctive Barbary falcon is represented by two subspecies of Falco peregrinus or is a separate species, F. pelegrinoides. The two species' divergence is relatively recent, during the time of the last ice age, therefore the genetic differential between them (and also the difference in their appearance) is relatively tiny. They are only about 0.6–0.8% genetically differentiated.
