We have power of life and death over many of the animals of the planet. The everyday choices we make can have tremendous effects, both malefic and beneficial, to the living fabric of our world.
Early in the last century, citizens of The U.S. Canada And Bermuda Formed a motion whose actions prevented the endangerment and possible extinction of what they sometimes known as the blue robin.
Bluebird populations had been waxing and waning in response to human activities since the time of European settlement. The clearing of the land for pastures orchards or gardens created hospitable spaces for the bluebird. Something as simple as a post hole in a fence or a crevice in a barn became home for a then thriving bluebird population. Early American agriculturalists bore a hate for the chicken hawk, they would often shoot, thinning out the population of bluebird predators. For a time the bluebird multiplied its number.
Sometime around 1900 starlings were introduced into the North American continent in Europe. It’s been said this was done merely as a novelty but it was an amusement that was to have catastrophic consequences for the bluebird population. Starlings evict bluebirds from their habitat and eat the berries which make up a substantial part of their diet.
As human folly had brought about the horrific debacle it’d take the actions of a broad coalition of individuals to rescue them from at least near oblivion. The answer by a concerned citizenry was to vertical birdhouses, [often referred to as nest boxes] across the range of bluebird habitation from the U.S., lower Canada and Bermuda.
Later in 1938 a blend of bird enthusiasts, garden clubs and the Missouri Highway Department established the National Bluebird trail.
The birdhouses were made of cedar and most importantly had entrance holes too small for the bigger invasive starling to enter [4cm]. They were made following a design invented by Dr. Thomas E. Musselman of Quincy Illinois. His mailbox type birdhouse allowed bird enthusiasts to view in the box by lifting the lid, enabling them to inspect inside. They then were able to determine not only if it was occupied but the condition of the occupants. This greatly eased the pressure on bluebird populations but other issues faced them.
Around the same time the starling was introduced another European species made its arrival, the house sparrow. Contrary to the starling the house sparrow can fit through holes fashioned for a bluebird.
As an invasive species house swallows enjoy no protection under law. It is a tricky task to place an animal to death, especially for bird fans but this is the only method of protection for bluebirds and other songbirds from these aggressors. Palm Bay Medical Marijuana have fashioned traps that fit into bluebird houses. After a sparrow is trapped it’s placed into a bigger trap that allows entry but pubs exit. The sparrows are gregarious and are attracted to others of the species.
Another way people can help the bluebird is to plant an assortment of berry bushes that bear fruit at different times of the year. Especially helpful are berries that last into winter the most taxing season.
