Order in Nature Photo 1: The natural world is full of order and regularity. It is very much visible with the bold patterns or dazzling colours that majority of the animals advertise – either to make one partner attractive to the other or to defence against the predator. But, then order can also be seen in the way animals behave.
Canada goose is the largest goose in the world. They fly in V-shaped formation which is considered to be more energy efficient particularly over long migratory routes and help in increase in flight range by 71%. In fact this type of V-formation is also used by military aircrafts while on flight missions. Canada geese communciate during their flights by honking and shifting positions during their flight in order to take turns.
They mate assortatively, larger birds choosing larger mates and smaller ones choosing smaller mates. They mate for life and have very low divorce rate. While the Female geese builds the nest, the male geese acts as a sentry watching the nest from a nearby location. On the ground the geese prefer a spot with fairly unobstructed view in all directions. Spacing of these pairs depends on the population density. When the population is large, the birds nest in view of one another.
The baby geese learn to swim in less than 24 hours after they are born and trained by their parents to dive 30-40 feet underwater by the time they are 1 day old. Soon they become more independent and groups of goslings join together to form gang broods of upto 100 goslings and learn to fly between 2-3 months of age.
Canada geees fly at an average speed of 40 miles per hour and reach upto 70 miles with strong wind. They can cover upto 3000. There are about 4~5million Canada geese in North America.

They both are translucent. While we as humans are able to identify plastic bags versus a moon jelly, marine species can’t. Plastic bags in the ocean are often mistaken by marine species like sea turtles for jellyfish. This causes blockages within their digestive system and eventually death! Not just that once in the ocean, plastic breaks down into tiny fragments known as micro plastic. These micro plastics are again mistaken by smaller organisms for food. We are only now realizing how big the problem is and scientists have already started seeing plastic in the tiniest organism to the animals on top of the food chain.
Humans produce over 300 million tons of plastic each year, a whooping 91% of plastic isn’t recycled. In the USA alone, around 102.1 billion plastic bags are used by Americans every year. More than 8 million tons of plastic is dumped into oceans. Millions of marine animals are killed from ingesting or becoming entangled in plastics.
We all have an obligation to do something to solve this growing problem. The least we can do is cut down the use of plastic and educate and inspire others to do the same.

The Great Dance on a Frozen Lake?
Great Blue Herons are the largest wading bird in New Jersey. With a wingspan of about 73 inches the Great Blue Herons are indeed great dancers and fighters!
They have elaborate courtship rituals including complex displays that help paris for strong bonds. Their mating displays include bill snapping, neck stretching, moaning calls, preening, circular flights, twin shaking, twig exchanging, crest raising and bill duels.
During Territorial fight, adults Herons display show an aggressive upright display followed by a forward display. The two Herons stab with their bills and buffet each other with their long wings and grip the opponent’s neck using its feet. These extreme aggressions are due to limited access to foraging sites. Deep water in summer and ice in winter restrict the access of Great Blue Herons to their foraging sites and possibly intensify competition among Herons.
Though the Great Blue Heron’s population in North America is stable, it is still classified as a species of special concern here in New Jersey — as the wetland destruction has caused a decrease in Heron population from their historic numbers.
In 2009 a total of 586 nests were counted in New Jersey.
