Tough species
The Canadian black goose can be said to beThe "big brother" of the species, is in the entire order of geeseformesThe largest speciesThere are no geese bigger than them in the whole world.
They have extremely pronounced physical features, with a long head and neck, tan feathers on their backs, and a tan neck, while their belly and buttocks are white, and their short tails are black, which makes themIt can be recognized at first sight
Among them, the males are larger than the femalesYou can stand up straight for more than a meter, and spread your wings for nearly two meters。Their infestation is not the same as that of Australia's hares.
AustralianHareBelongsSolitary animalsEach has its own territory, so they will quickly spread throughout Australia, making them miserable, reaching nearly 10 billion at the peak, and eventually passing throughUse "Creature**" to control them, despite this, they remain in2-300 million
The Canadian Black Goose is different, they love itIn droves, good at swimming and diving, this is their nature, and the communication between them is called "quack", this kind of horde species, thatThe cacophony of cries came and went
Calls are the most effective way to convey information, and like most species, when they spot an intruder, they will chirp loudly and the whole flock will become agitatedYou think they're scared and ready to run away?
That's wrong, they're starting to get angryOne by one, they made a "fighting posture".Always ready to fight to the death against invaders, they will never abandon their nests and habitats.
In our impression, the geese are all autumn to spring, we see their figure is generally in the sky, a line of geese flying over, but with the change of the environment, we gradually difficult to see the rows of geese.
The main food of the Canadian black goose turned out to bePlantsWith such a large physique, which does not prey on small fish, and likes to eat grass and moss, is it healthier to eat vegetarian?It's no wonder that they can live up to 24 years in the wild.
Not only that, but their reproductive ability is also quite strong, and their breeding period is every yearMarch-August,It takes nearly a month to hatch their own babies, and after the chicks are born, their mothers take care of them for a month or two or more.
It's all because of love
Because of their unique appearance, theyAt first, it was also extremely popular with the public in Canada, and even revered asNational birdIt is their nature to migrate in autumn and spring, and Canada with a suitable climate has become a holy place for them to spend the winter.
In the past, Canadian black geese were threatened by hunters, which led to their low numbers in Canada, so they started to be seen more oftenArtificially reproducedto increase their number, evenLaws were enacted to protect them.
But after being bred and bred in captivity, they found these Canadian black geese released into the wildLost the instinct to migrate, settled in Canada in this climate.
In the beginning, Canada** also thought it was a good thing, so that people could see the Canadian black goose oftenTheir long lifespan and ability to reproduce have allowed their numbers to increaseThey can be found on the shores of lakes in Canada.
They are also quite smart, and once someone photographed hail outside, but these Canadian geese wereRaise your head one by oneIt looks like they're facing the hail, but they're actually dodging the hailRaising your head can be a great deal of chance of being hit on the head by hailAt the same time, they were not idle, but concentrated on watching the hail falling from the sky to better dodge.
At that time, people only thought they were smart, and they didn't realize it"Black forces".are making ambitious attempts to occupy Canada, theirGross body typePlusProtection of the lawIn Canada, which has almost no natural predators, it began to reproduce wildly.
Naturally, these artificially bred offspring do not have the ability to migrate, and over time they become calledCanada goose, and what follows is an occasional occurrence"Man-Goose Wars".Visitors to the wetland park are often perceived as intruders and attacked by the "geese".
This is their nature to protect their territory, and at that time people were not aware of their "ambition", and the lakeside was only a base for their secret breedingTheir goal does not stop there, but the city of humanity.
As their numbers increased, the lakes in the wild could no longer satisfy them, so they strode into the city's parks, herbivorous themThe lawn of the park is not lightThey also occupy the ponds in the park, and their excrement is everywhere in the park meadows.
While they expand their territory, they also threaten the safety of humans, and they like to fly"Malignant incidents".In '09 they flew into the airport take-off area, and the plane hit them shortly after takeoff, and both engines of the plane lost power, and finallyCrash landing in a lake.
This is also the first time that people have begun to be "alert" to them, but they are praised as national birds and are protected by the law, so they can only beWatching them "arrogant".
After that, they began to swagger into the city, shuttling through the middle of the road, and seeing passers-by only made them feel threatenedIt's a mouthful, and it also uses a "flying kick".
In the city, they learned without a large meadowRummaging through trash cans, the contents are everywhere, garbage is everywhere, and there is also their excrement.
Signs are erected by ponds of all kinds in Canada"Humans are forbidden to play in the water"., not to protect the Canadian black goose, butIn order to protect people from attacks,At the same time, with their arrival, the water in the pond is also full of their droppingsNot going into the water is also to avoid human illness.
Black geese in the wild will also fly into the farmer's house, gnaw on the owner's backyard lawn, and finally leave a pile of dung, which almost reaches the point of "boiling public resentment".Begin to allow professional hunters to perform proper huntingBut they are shrewd by nature and are so numerous that these hunters alone can kill very few of them.
Ordinary people also hide far away when they see them in the streets and alleys, so they will not take the initiative to approach and kill, which also leads to themThe number has increased instead of decreasing.
This is mainly the folk customs of CanadaThe inhabitants of the city don't want to hunt themAnd the rural farmers do not have so much energy, as long as they do not enter their own yards, they will not take the initiative to become enemies of them.
So they are still rampant in the streets of Canada, despite thisCanada** still can't cancel their insurance**,Because once it is canceled, it will inevitably attract a lot of hunting, although it can reduce their numbers, but hunters who are carried away by profit will not care about whether they will become extinct.
Conclusion
Canadian Black GooseRun rampant on the streets, parks, and even intrude into residents' backyardsAlthough a series of countermeasures have been taken, to no avail, their number is still growing.
This is the caseSimilar to the pheasant in the northeast of our country,It was once hunted to the point of near extinction, and then to the frenzied reproduction after being protected, destroying crops, but it was also not allowed to be hunted again.
Now in Canada their number has reachedNearly 5 million, but they are still protected animals, this one"The Battle of the Wild Goose".And the fun will continue.
