An overcast day in Churchill provided the perfect setting for some beautiful photographs of the natural surroundings of the region. Birds are nesting and the wildflowers are blooming all over the tundra. Beluga whales are arriving in the Churchill River in pods and we will be posting photos soon from some Natural Habitat Adventures trips in July. Enjoy these Awesome photos!
This exquisite close – up image of an Arctic Tern incubating eggs on its nest shows just how camouflaged their eggs are. It took me awhile to even see the one egg in front of the tern since it blends so well into the tundra. Arctic terns lay 1 – 3 eggs and both the male and female incubate the eggs for up to 22 days. After birth the parents supply small fish up until they fledge at three to four weeks old. Female and male Arctic terns mate for at least a year and can mate for life. Females lay eggs once a year. Terns live on average up to 34 years.
The photo of the three Arctic tern eggs illustrates the magnificent camouflage adaptation the eggs have developed over many years. The way animals and their eggs adapt to the environment using camouflage is fascinating. Survival of species depends on these slight changes over periods of time. The faster a species can adapt the longer they can survive in nature.
These two photos of Precambrian shield rolling toward the Hudson Bay show how the rocks have been smoothed over in previous eras by ice and water covering them. If you look closely you can see marks or “striations” caused from rocks embedded in the bottom of glaciers that were dragged over them during the slow movements of the massive ice formations. It’s quite interesting to search out these striations while hiking over the shield in Churchill.
