I am a professional photographer living in Winnipeg, Canada. My special interests are people and nature photography. I have been taking pictures for over 35 years. Winnipeg has a very agreeable climate in the Spring, Summer and Fall. Winters can be quite cold especially in January. No matter what season, picture taking opportunities in Winnipeg are excellent.

Caption: A bottlenose dolphin at the Mirage Hotel's Secret Garden shows off for visitors. Bottlenose dolphins live in groups typically of 10-30 members, called pods, but group size varies from single individuals up to more than 1,000. Their diets consist mainly of forage fish. Dolphins often work as a team to harvest fish schools, but they also hunt individually. Dolphins search for prey primarily using echolocation, which is similar to sonar. They emit clicking sounds and listen for the return echos to determine the location and shape of nearby items, including potential prey. Bottlenose dolphins also use sound for communication, including squeaks and whistles emitted from the blowhole and sounds emitted through body language, such as leaping from the water and slapping their tails on the water surface. There have been numerous investigations of bottlenose dolphin intelligence. Research on bottlenose dolphins has examined mimicry, use of artificial language, object categorization and self-recognition. Their considerable intelligence has driven interaction with humans. Bottlenose dolphins are popular from aquarium shows and television programs such as Flipper. They have also been trained by militaries to locate sea mines or detect and mark enemy divers. In some areas, they cooperate with local fishermen by driving fish into their nets and eating the fish that escape. Some encounters with humans are harmful to the dolphins: people hunt them for food, and dolphins are killed inadvertently as a bycatch of tuna fishing. The common bottlenose dolphin is grey in color and may be between 6.6 ft. and 13 ft. long, and weigh between 330 lbs. and 1,400 lbs. Males are generally larger and heavier than females. In most parts of the world the adult's length is between 8.2 ft. and 11 ft. with weight ranges between 440 lbs. and 1,100 lbs. Newborn calves are between 2 ft. 7 in. and 4 ft 7 in. long and weigh between 33 lbs. and 66 lbs. The dolphins have a short and well-defined snout that looks like an old-fashioned gin bottle, which is the source for their common name. Like all whales and dolphins, though, the snout is not a functional nose, which has evolved instead into the blowhole on the top of their heads. Their necks are more flexible than other dolphins' due to five of their seven vertebrae not being fused together as is seen in other dolphin species.
