Very rare photos (Frozen Niagara Falls)

This image is displayed on the Niagara Falls Public Library website with the title "American Falls Frozen over with People on the Ice". According to information associated the image, it began circulating on the Internet in 2003 but the original source and date is not known.

The image is also featured on Niagara Falls live.com, and its position in the text suggest that it may be future to show an event in 1848 when the river really stopped flowing completely for a few hours due to an ice jam upstream. Though, it is unclear if the image depicts the actual event describe, or is only used as a general illustration of an ice bridge.

American Falls Frozen Over With People on the IceThis image was apparently derived from an original color postcard titled "Cave of the Winds in Winter Niagara Falls" which was mailed in August 1911. Accurately when the image was created is unclear. The image is also featured on the website of Ellis House, a Bed and Breakfast at Niagara Falls.

Cave of the Winds in Winter Niagara Falls This image seems to be a cropped version, of a photograph titled "American Falls frozen over" that was taken in 1936. Comments with the uncropped image explain "The miraculous result of a cold winter, the American Falls totally froze in 1936. Notice the tiny human forms at the base of the Falls giving an idea of the density of the ice."

American Falls frozen overThis image is also included on the Niagara Falls Public Library as well as titled "Great mass of frozen spray and ice-bound American Falls Niagara", by a date of 1902. It originally formed part of a stereo image, a popular medium at the time.

Bush Dog (Rare animal)

The Bush Dog is a canid found in Central and South America, including Panama, Colombia, Venezuela, Bolivia, Peru, Ecuador, the Guianas, Paraguay, northeast Argentina, and Brazil. In spite of its extensive range, it is very rare; it was originally discovered as fossils in Brazilian caves and thought to be extinct. It is the only living species in its genus, Speothos.

Bush DogIn Brazil it is called cachorro-vinagre or cachorro-do-mato. In Spanish-speaking countries it is called perro vinagre, zorro vinagre, perro de agua or perro de monte.

The Bush Dog has soft long brownish-tan fur, with a lighter reddish tinge on the head, neck and back and a bushy tail, while the underside is dark, sometimes with a lighter throat patch. Adults typically have 55–75 cm (22–30 in) of head and body, plus 13 cm (5 in) of tail, and weigh 5–7 kg (11–15 lb). Legs and snout are short relative to body length: the typical height is only 25–30 cm (10–12 in). The teeth are adapted for its carnivorous habits, and uniquely for an American canid, the dental formula is for a total of 40 teeth. The Bush Dog is one of three canid species with trenchant heel dentition, a unicuspid talonid on the lower carnassial molar that increases the cutting blade length.

Bush dogIt is a carnivore and hunts during the day, preferably in wet savannahs and tropical and equatorial forests. Its typical prey is the Paca, a large rodent. Although it can hunt alone on occasion, the Bush Dog is usually found in small packs of up to 10–12 individuals, which can bring down much larger prey. It may be the most gregarious of the South American canid species. Bush Dogs have skin growing between their toes, which allow them to swim more efficiently. It uses hollow logs and cavities for shelter. Pack-mates keep in contact with frequent whines, perhaps because visibility is poor in the undergrowth where the animal typically hunts.

The gestation period is 63 days, and a litter can have up to six dark grey pups. Lactation lasts approximately 8 weeks. The Bush Dog is sexually mature at 1 year and lives for about 10 years.
