RED-TAILED HAWK: THE URBAN-SUBURBAN-EXURBAN RAPTOR KING

Chances are that if you see a hawk, it is most likely a Red-tailed. Unlike so very many bird species, the Red-tailed Hawk population has increased over the past one hundred years. The global population hovers around 2 million and its success is due largely to the bird’s ability to adapt to a wide range of habitats, including urban, suburban, and exurban developments. As long as their is some open space, trees or tree-like structures for perching, and small mammals, you will find Red-tailed Hawks.

The Red-tailed Hawk seen here was photographed at Parker River on the luxuriously warm Saturday afternoon last weekend. There were loads of people out walking and enjoying the sunny skies. It was difficult to tell if the Hawk was simply extremely tolerant of people or if he were struggling with an injury or illness. He stayed for a very long time in a small area, over an hour, but flew periodically to hunt in the thicket below (unsuccessfully), and then flew easily back up to the phone lines and trees. At one point, he almost flew into a car driving into the refuge, missing the windshield by inches. I hope that after the gates closed at sundown the Red-tailed was able to right himself and find a tasty dinner.

The House Built of Spite

Pink house, pink clouds, pink marsh sea – 

The lonely pink house of Plum Island’s Great Marsh is today only visited by hawks and Snowy Owls, perching to scan the surrounding vista for their next meal.

Local lore has it that the house was built in 1922 by a couple who were in the process of divorcing and sorting their affairs. The wife asked that the husband build a replica of their Newburyport family home. She did not say where the house was to be sited. Out of spite, he built the house atop the isolated salt marsh, with only saltwater plumbing.

The Pink House has not been occupied since the early 2000s and looks worse with each passing year. Last winter I was at the refuge for a program held at the PRNWR headquarters. After the event I tried to drive towards Plum Island but with sea water gushing in from the marsh, the road in front of the house was dangerously impassable.

The house is FREE, if only you will either take it off the marsh or give Parker River National Wildlife Refuge a few acres of comparable land. The second option allows for the house to stay in its current location. Read more here: Free Pink House of Newbury: Take Me I’m Yours

Red-tailed Hawk Soaring Through the Neighborhood

Walking with Charlotte and out from the trees there suddenly appeared a shadowy bird, swooping very low and closely over our heads. A Red-tailed Hawk!

He perched for a moment on a nearby limb, turning his head in all directions, hungrily triangulating the landscape for a tasty meal. Next he flew to a nearby telephone pole, and then over the houses towards the Harbor.

A few minutes later the Red-tailed reappeared, followed by several crows noisily haranguing and giving him the business, in no uncertain terms!

THIRD IN ONE WEEK JUVENILE RED-TAILED HAWK BEING TREATED FOR RAT POISON

Our local wildlife rehabbers Jodi Swenson and Erin Hutchings (CAPE ANN WILDLIFE) are on the front lines of trying to save our raptors from rodenticide poisoning. They have treated three juvenile Red-tailed hawks just this week alone. Two perished and a third is barely hanging on. Tufts does necropsies on all dead raptors-98 percent have rat poison in their system. Please see previous post about safer alternatives to the new second-generation deadly poisonous rodenticides.

Alternatives to Deadly Second-generation Rat Poison

Recently we shared a story from the Snowy Owl Project that this year Snowy Owls have remained in Massachusetts throughout the summer. We also posted about eight cases of Snowy Owl deaths by rat poison, in Massachusetts, which has been documented during the present Snowy Owl irruption of 2017-2018. Buried in the post was a link to an article from Audubon, “Poisons Used to Kill Rodents Have Safer Alternatives,” which is about alternatives to the new second-generation rodenticide that is killing our native predator population. These are the very birds and animals that we want to support because they eat rats and mice. This is not an abstract problem; Cape Ann Wildlife rehabbers Jodi Swenson and Erin Hutchings are caring for almost daily dying wildlife that has been poisoned to death by second-generation rodenticide, and the problem is mushrooming. Second-generation rodenticides also kill pet dogs and cats! 

Jodi and Erin recently shared the above photo of a juvenile Red-tailed Hawk they had been treating for rodenticide poisoning, which tragically did not make it. These birds are victims of second-generation anticoagulant rodenticides used by exterminators, businesses, farmers, and homeowners.

The brand names are Havoc, Talon, Generation, d-Con, and Hot Shot. Do not buy these products because they contain the deadly indgredients brodifacoum, bromadiolone, difethialone, and difenacoum.

“Both first- and second-generation rodenticides prevent blood from clotting by inhibiting vitamin K, though the second-generation products build to higher concentrations in rodents and are therefore more lethal to anything that eats them.

What makes second-generation rodenticides so non-selective is that they kill slowly, so rodents keep eating them long after they’ve ingested a lethal dose. By the time they expire, or are about to, they contain many times the lethal dose and are therefore deadly to predators, scavengers, and pets.

There’s no safe place or safe delivery system for second-generation rodenticides. After a rodent partakes, it stumbles around for three to four days, displaying itself as an especially tempting meal not just for raptors but for mammalian predators, including red foxes, gray foxes, endangered San Joaquin kit foxes, swift foxes, coyotes, wolves, raccoons, black bears, skunks, badgers, mountain lions, bobcats, fishers, dogs, and house cats—all of which suffer lethal and sublethal secondary poisoning from eating rodents. Deer, non-target rodents, waterfowl, waterbirds, shorebirds, songbirds, and children suffer lethal and sublethal poisoning from eating bait directly.”

Here in a nutshell are alternatives to second generation rat poison. Please read the complete article, which goes in to much greater detail to better understand why this is happening, which companies are responsible for creating the toxic poison, which companies are taking it upon themselves to ban second-generation rodenticides (Walgreens, yes, Home Depot, no), and how you can help.

  1. Prevent a rodent infestation by keeping waste in tightly covered garbage pails and compost bins.
  2. RATS! (Raptors are the Solution) – a national alliance of citizens, nonprofit groups, and local governments that educates consumers and municipalities about safe methods of rodent control and the dangers of second-generation poisons. MASS-RATS is the newly formed state chapter of RATS.
  3. . Hungry Owl Project – delivers safe, effective rodenticide in the form of Barn Owls! This organization also advocate for other predators—coyotes, foxes, mountain lions, badgers, skunks, bobcats, raccoons, opossum.
  4. When natural rodent control is not possible in urban areas: single- and multiple-entrance snap traps, electrocuting traps, glue traps (provided you use them only indoors and frequently dispatch stuck rodents), and even first-generation baits with these active ingredients: chlorophacinone, diphacinone, diphacinone sodium salt, war-farin, and warfarin sodium salt.
  5. The “Better Mouse Trap” – Take a metal rod, run it through holes drilled in the center of both lids of an emptied tin soup can so the can becomes a spinning drum. Fasten both ends of the rod to the top of a plastic bucket via drilled holes. Coat the can with peanut butter, and fill the bucket with water and a shot of liquid soap (to break the surface tension and thus facilitate quicker, more humane drowning). Mice and rats jump onto the can, and it spins them into the water.

SNOWY OWLS IN MASSACHUSETTS IN AUGUST!?!

The Snowy Owl Project shares that not one, not two, not three, but four Snowy Owls remain in our area! This is highly unusual for August because most Snowies have left Massachusetts by May.

They are finding finding plenty to eat. The owls are being closely monitored and thus far have no health issues. This is the time of year that Snowy Owls molt, so if you see one, it may be brown and missing some feathers.

Tragically, a Snowy was recently rescued at Logan Airport and was taken to Tufts, where it died of rodenticide poison. That brings this year’s total to eight that have been killed by rat poison. Imagine if in every region, this many were killed annually by rat poison. It’s no wonder the species is struggling, despite occasional irruptive years.

Oregon Coast National Wildlife Refuge shares the following:

Do you have unwanted mice and rats around your home? Do you also have birds of prey and beloved pets using that same area? If you do, consider the potential deadly consequences of using toxic rodenticides on more than just the rodents.

Dan Vickers snapped this photograph of a Red-tailed Hawk eating a poisoned rat. The blue color you see in the gut of the rat is a fat-soluble dye used in anticoagulant rodenticides. Unfortunately, it is not uncommon for rat poisons to accumulate in the food web. Once this hawk consumes the poison, it too can die.

Please help minimize wildlife exposure to pesticides and consider the collateral damage and danger for other mammals, birds of prey, domestic pets, and humans.

We Love You Too Snowy Owl!

For the past several days there has been a remarkably tolerant Snowy Owl feeding and perching on the rocks at Atlantic Road. Perhaps she (or he) is the same Snowy that has been noticed on the backshore over the course of the past month. I write tolerant because this Snowy was perched about fifteen feet from the sidewalk and neither traffic nor birdwatchers seemed to faze her much. As word has gotten out, her fan club has grown, so much so that there was a bit of a traffic jam today. Every several hours I stopped by to check on her whereabouts. At 2:00 today, she had only moved about a foot from where she was at daybreak. By sundown, she had flown up onto the rooftops of an Atlantic Road resident.
Many thanks to Kate for all her text alerts letting me know when the Snowy was on the backshore!

Early morning and the Snowies face and talons were bloodstained, which is a very positive sign that she is feeding well. Snowy Owls wintering over in our region eat rabbits, rodents (lots of rats), songbirds, and sea ducks. Being good stewards of the Snowies means not applying rat poison around your home or business. There are several methods equally as efficient in killing rats as rat poison. When a bird of prey such as a Peregrine Falcon, Snowy Owl, Red-tailed Hawk, or Bald Eagle ingests a rat that has eaten rat poison, the raptor becomes sick and will usually die.

The Snowy spent the better part of the day mostly dozing, preening, cleaning her talons, and puffing her feathers for warmth. At one point she pushed her face into a snow patch but I couldn’t tell if it was to drink or to wash.

For a moment the Snowy sat bolt upright from a loud bang heard in the distance, but generally, she was a satiated and sleepy owl.
