With habitat disappearing the Red Shouldered hawk is starting to show up in more urban areas.
Often heard before being seen the Red Shouldered Hawk is one beautiful predator that faces many obstacles. With human population growing the need for housing is devouring this birds native habitat like a dark plaque.

The Red shouldered hawk is a lucky survivor of the pesticides that interfered with reproduction in the 1970′s. The most notable pesticide being DDT. I wrote an article on The Bald Eagle and the troubles it faced with DDT. The Red shouldered hawk had the same fight and luckily the pesticide was removed from use before it wiped out entire bird populations.
This Hawk is a great predator and had it been wiped out, the problems would have been huge. The Red shouldered Hawk loves small mammals ( rats) and is a key to controlling the population of these pests. Without the Red shouldered Hawk the rat population would explode and we could have a serious problem.
Now you may be thinking that doesn’t sound like a big deal. So there would be a few more rats. Rats are known to carry disease and they can be very destructive when creating their homes. Let’s have a little history lesson and I am sure you will then understand the importance of natural population control from predators.
The Black plaque or bubonic plaque was a massive and deadly pandemic that had widespread destruction.
Taken from the Wikipedia.
” From 1347 to 1351, the black death, a massive and deadly pandemic, swept through Asia, Europe and Africa. It may have reduced the world’s population from 450 million to between 350 to 375 million. China, where it originated, lost around half of its population (from around 123 million to around 65 million), Europe around 1/3 of its population (from about 75 million to about 50 million) and Africa approximately 1/8th of its population (from around 80 million to 70 million). This makes the Black Death the largest death toll from any known non-viral epidemic. Although accurate statistical data does not exist, it is thought that 4.2 million died in England (1/4 of the population), while an even higher percentage of Italy’s population was likely wiped out. On the other hand, Northeastern Germany, Bohemia, Poland and Hungary are believed to have suffered less, and there are no estimates available for Russia or the Balkans.”
So what do rats and the red shouldered hawk have to do with it?
Taken from the Wikipedia.
” Bubonic plague is mainly a disease in rodents and fleas (Xenopsylla cheopsiss). Infection in a human occurs when a person is bitten by a flea that has been infected by biting a rodent that itself has been infected by the bite of a flea carrying the disease. The bacteria multiply inside the flea, sticking together to form a plug that blocks its stomach and causes it to begin to starve. The flea then voraciously bites a host and continues to feed, even though it cannot quell its hunger, and consequently the flea vomits blood tainted with the bacteria back into the bite wound. The bubonic plague bacterium then infects a new victim, and the flea eventually dies from starvation. Any serious outbreak of plague is usually started by other disease outbreaks in rodents, or a rise in the rodent population.”
Now it all makes sense!
Many of today’s scientists believe that the black plaque was viral and not caused by rats but we will never know. So now lets think about an explosion in the population of rats due to the fact the the Red shouldered Hawk was rendered extinct from pesticides. It sounds like a very very bad thing.
The Red shouldered Hawk’s diet also consists of Birds, Reptiles, Amphibians, Insects and others. They are very territorial and sometimes offspring will return to the same territory for many years. The longest recorded active territory of the Red shouldered Hawk was 45 years.
Everything in Nature has it’s place and it is important to keep the fragile balance.
