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

Our local wildlife rehabbers Erin Hutchings and Jodi Swenson (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 past 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. There are much safer and less cruel alternatives to second-generation rat poison 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 Owl 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.TOXIC LUNCH!

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 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 in the distance, but generally, she was a satiated and sleepy owl.

PARKER RIVER NATIONAL WILDLIFE REFUGE PART ONE

Parker River National Wildlife Refuge Part One

I am in the midst of doing research for the Piping Plover film project and have found the Parker River National Wildlife Refuge to be a great resource. Recently I met a terrific warden there, Jean, and she gave me a copy of the historic brochure written in 1947 by Rachel Carson about the refuge. The brochure was reprinted and if you inquire, they may still have some copies in the back office. You can also download it at this link: Rachel Carson Parker River Wildlife Refuge brochure

The brochure provides an early history of the refuge and is a fascinating view of mid-century conservation. And, too, it is a tremendous example of Carson’s thoughtful and thought-provoking style of writing.

Barred Owl hunting – The refuge provides over 300 species of migratory and resident birds with vital habitat.

Some interesting facts about the refuge —

Located along the northeastern coast of Massachusetts, the Parker River National Refuge includes lands that lie within the three towns of Rowley, Ipswich, and Newbury. We think of Plum Island as the heart of the refuge. The wildlife refuge also consists of a range of diverse habitats and geographic features; over 3,000 acres of salt marsh, freshwater marsh, shrub lands, a drumlin, cranberry bog, salt pannes, beach and sand dunes, and maritime forest. The land is not conserved to revert back to a wild state, but is intensely managed in order to preserve and maintain the diversity of wildlife habitats.parker-river-national-wildlife-refuge-wardens-headquarters-copyright-kim-smith

The original warden’s headquarters

Unlike our national parks, which preserves parklands and historic buildings, and are designed for people, a national wildlife refuge is established first and foremost for wildlife and their habitats, not for people. The preservation of wildlife is the number one priority of all our national wildlife refuges.plum-island-sunrise-copyright-kim-smith

sandy-point-parker-river-national-wildlife-refuge-copyright-kim-smithPlum Island is a barrier island and especially noteworthy for providing critical habitat for Piping Plovers.

The Parker River National Wildlife Refuge was established in 1942 to help species of waterfowl that migrate along the Atlantic Flyway. There were three sharp declines in waterfowl populations in the early half of the 20th century, notably the American Black Duck, and national wildlife refuges all along the Atlantic coast were created in response to the precipitously low numbers.

As we can see with our local Niles Pond, Henry’s Pond, and Langsford Pond shorebirds, waterfowl, and myriad species of wildlife thrive where they have easy access to both fresh water and salt water. The three bodies of fresh water that you see in the refuge look like ponds but they are actually manmade impoundments, created by dams and are highly controlled by a series of dykes and pumps.parker-river-wildlife-refuge-impoundment-pump-copyright-kim-smith

Salt Island Impoundment Pump

Parker River provides pristine habitats for a wide variety of mammals, insects, fish, reptiles, and amphibians. Hunting birds such as owls, hawks, osprey, eagles, herons, and egrets find an abundance of food at the wildlife refuge. Whenever at Parker River I never not see a raptor!

Transfixing Owl Eyes

Because owls mostly hunt at night their eyes are very efficient at collecting and processing light. To protect their extraordinary eyes, owls are equipped with three eye lids; an upper and a lower lid, and a third lid that diagonally closes across the eye. This action cleans and protects the eye.

FREE PINK HOUSE OF NEWBURY!

Take Me I’m Yours! A FREE HOUSE! You Only Need To…pink-house-newbury-plum-island-2-copyright-kim-smith

Many admire the Pink House that you see on the way to Plum Island and the Parker River National Wildlife Refuge, so much so that when it came time to demolish there was public outcry. The US Fish and Wildlife Service has agreed to preserve the house by either of these two conditions. Option number one: a person can take ownership if they are willing to move the house off the land, or option number two is that if you own several acres of comparable land near the refuge, you can exchange the land for the house. Option two allows the house to stay in its current location.

Perhaps the Pink House could become a community or art center. The building has been deemed structurally sound, although there is quite a bit of asbestos that needs removing.

The Pink House is the last house remaining on the refuge. All other homes and farms were either sold or taken by eminent domain; the very last on Stage Island was demolished just this past year.pink-house-newbury-plum-island-copyright-kim-smith
