  • It was nice to have a brief moment to indulge in my passion for macro photography. There was so much insect life attracted to this little green oasis, including these beautiful mating damselflies.

  • Steller sea lions forage near shore and pelagic waters.They are also capable of traveling long distances in a season and can dive to approximately 1300 feet (400 m) in depth. They use land habitat as haul-out sites for periods of rest, molting, and as rookeries for mating and pupping during the breeding season. At sea, they are seen alone or in small groups, but may gather in large "rafts" at the surface near rookeries and haul outs. They are capable of powerful vocalizations that are accompanied by a vertical head bobbing motion by males.<br />
Steller sea lions are opportunistic predators, foraging and feeding primarily at night on a wide variety of fishes (e.g., capelin, cod, herring, mackerel, pollock, rockfish, salmon, sand lance, etc.), bivalves, cephalopods (e.g., squid and octopus) and gastropods. Their diet may vary seasonally depending on the abundance and distribution of prey. They may disperse and range far distances to find prey, but are not known to migrate.<br />
Steller sea lions are colonial breeders. Adult males, also known as bulls, establish and defend territories on rookeries to mate with females. Bulls become sexually mature between 3 and 8 years of age, but typically are not large enough to hold territory successfully until 9 or 10 years old. Mature males may go without eating for 1-2 months while they are aggressively defending their territory. Males may live up to 20 years and females to 30 years. Females start breeding at 3-7 years and spend the next two decades either pregnant or lactating. Females are bred in June, but the fertilized egg does not implant until October. Single pups are born the following June, with birthdates at southern rookeries earlier than births at northern rookeries. Twins are rare. Pups suckle from 1 to 3 years, with most apparently weaning after their first winter.

  • This was one of the most amazing things that I witnessed on the trip. I was on a beach where large numbers of squid were beaching themselves after mating. Once they were stranded they started flushing red rapidly back and forth along their bodies, presumably as a sign of agitation. Then I saw several large moray eels wriggling through the shallow water following them right up to the water’s edge and then to my amazement I watched them engulf and swallow the squid whole in the blinking of the eye. I could see why the moray eel has such a large head with wrinkled skin to allow it to swallow large prey whole rather like a snake.

  • When it comes to food, black bears are creatures of opportunity. There are certain patterns of food-seeking which they follow. Upon emerging in the spring, freshly sprouted green vegetation is their main food item, but they will eat nearly anything they encounter. Winter-killed animals are readily eaten, and in some areas black bears have been found to be effective predators on new-born moose calves. As summer progresses, feeding shifts to salmon if they are available, but in areas without salmon, bears rely on vegetation throughout the year. Berries, especially blueberries, ants, grubs, and other insects help to round out the black bear’s diet.<br />
For most of the year, black bears are solitary creatures, except from June through July when mating takes place. The cubs are born in their dens following a gestation period of about seven months. The cubs are born blind and nearly hairless, weighing in under a pound. One to four cubs may be born, but two is most common. Cubs remain with their mothers through the first winter following birth.As with brown bears, black bears spend the winter months in a state of hibernation. Their body temperatures drop, their metabolic rate is reduced, and they sleep for long periods. Bears enter this dormancy period in the fall, after most food items become hard to find. They emerge in the spring when food is again available. Occasionally, in the more southern ranges, bears will emerge from their dens during winter. In the northern part of their range, bears may be dormant for as long as seven to eight months. Females with cubs usually emerge later than lone bears. Dens may be found from sea level to alpine areas. They may be located in rock cavities, hollow trees, self-made excavations, even on the ground. In Southeast Alaska, black bears occupy most islands with the exceptions of Admiralty, Baranof, Chichagof, and Kruzof; these are inhabited by brown bears. Both bear species occur on the southeastern mainland.

  • Between mid-November and March is when moose typically lose their antlers; younger moose keep their antlers until later in the winter and it is usually only two year old moose that may still be adorned with their antlers come March. Moose are the largest living member of the deer family (Cervidae) and fittingly bear the largest set of antlers. Moose antlers are usually paired and shaped like the palm of a hand with outstretched fingers, thus the expression palmate. After a male moose reaches one year of age he starts to grow antlers that increase in size becoming more elaborate with more points and heavier for each new set of antlers he grows until he reaches his prime. After a male (Bull) moose reaches his prime the antlers start to recede each year until the moose dies. Every year the cycle is the same. In the spring antlers begin to grow from the skull covered with a tissue called “velvet”. By September the growth has completed and the velvet dries and falls off. Moose will often aid the removal of the velvet by rubbing their antlers on trees and shrubs (on occasion they’ll eat the velvet too!). The continuous rubbing on trees, combined with the dried blood and dirt will give the Moose Antlers the brown colour in the fall. They do not serve a useful purpose until the fall and during the mating season (called the Rut).<br />
This was during one of my best winter experiences in Southeast Alaska. There was such a great feeling of wildness and solitude up in Adam's Inlet. Very few boats go right up into Glacier Bay during the winter, and certainly not deep into Adam's Inlet. It was so peaceful up there in winter. It has always been my dream to spend a whole winter camped with the moose and wolves up Adams Inlet.

  • Madagascar is home to about half the world’s chameleons, including both subfamilies, typical chameleons and dwarf chameleons (Brookesiinae). Chameleons are small to mid-size reptiles that are famous for their ability to dramatically change colours. Contrary to popular belief, they do not change colours to match their surroundings. Instead colour is usually used to convey emotions, defend territories, and communicate with mates. They have two layers of specialized cells that lie just beneath the lizard’s transparent outer skin. The cells in the upper layer, called chromatophores, contain yellow and red pigments. Below them is another layer of cells called guanophores, containing the colourless crystalline substance guanin, which reflect the blue part of incidental light. If the upper layer of chromatophores is yellow, the reflected light becomes green (blue plus yellow). A layer of dark melanin containing melanophores is situated under the blue and white light-reflecting guanophores. These melanophores influence the lightness of the reflected light. All these different pigment cells can relocate their pigment, thereby influencing the colour of the light that is reflected.<br />
Other notable features are bulging eyes that move independently, enabling them to be able to look ahead and behind at the same time, feet with paired toes fixed in a grasping position, and the existence of horns or crests on the heads of many species. Additionally, arboreal species have prehensile tails used for grasping objects when climbing, and some species have long extensile tongues for catching insects or small vertebrates at a distance often greater than their length.<br />
They are diurnal, solitary, and often aggressive towards members of their own species (marked by rapid colour change and aggressive posturing). They are opportunistic hunters that wait for their prey, and move in a curiously, tentative swaying manner. Their bodies are very narrow enabling them easier passage through foliage.
