A Visit to Tri-State Bird Rescue and Research

Thursday, November 17th, 2022

by Meaghan Lyon, Wildlife Biologist

When CWF biologists encounter an injured bird while doing field work, we usually turn to Tri-State Bird Rescue and Research for help.  A recent visit to the Tri-State Bird Rescue and Research facility located in Newark, Delaware provided great insight into the efforts that go into ensuring that injured and oiled birds have a second chance in the wild.  Their mission is to provide professional, compassionate rehabilitation to native injured and orphaned wild birds and contaminated wildlife, and to promote their stewardship through education and humane research.

The facility has two programs, the Wild Bird Clinic and Oiled Wildlife Response.  With more than 40 years of experience, the Wild Bird Clinic provides expert medical care, housing, and diets to injured, orphaned, and oiled native wild birds.

Inside the Oil Response Center you see large buckets to wash birds and other wildlife. Hoses hang from the ceiling to provide easy access and to avoid hazards.

Stormy Spring Impacts Osprey Productivity

Tuesday, November 15th, 2022

An osprey nest with hatchlings on May 16, 2022. One of many nests that eventually failed to produce young this year.

Whenever we look at how ospreys are faring, weather is always taken into account. When we summarize and report on the results of our summer osprey nesting surveys, we also look at the local climate. Being situated along the Atlantic coast, our weather is influenced by the ocean. As aerial predators of fish, ospreys are reliant on favorable water conditions to forage.

Preliminary results of the 2022 New Jersey Osprey Project Census show that the osprey population was not as productive this year as they have been over the past ~20 years. This was largely due to a low pressure system (nor’easter) that stalled off the coast in early May — when the majority of pairs were incubating eggs. The strong onshore winds caused moderate coastal flooding, windy conditions, increased wave action and water turbidity, which made it more difficult for ospreys to find and catch prey in coastal waters. Males do 100% of the foraging from the onset of egg laying until young begin to fledge, so when they are unable to provide food, females must abandon their nests and eggs to forage for themselves. The nor’easter in May appears to have affected the outcome of many coastal nests and in some cases, complete colonies. Of course there are many other causes for nest failure but this year weather played a major role.

In the coming weeks CWF staff, NJDEP Biologists, and a handful of dedicated volunteers will descend onto the coastal saltmarshes of New Jersey to conduct a census of nesting ospreys. The last census was conducted in 2017 when 668 nesting pairs was recorded. They will survey remote areas of back bays by boat. Nests are surveyed in a variety of methods, with ladders being the traditional method, which allow for closer inspection of nests and banding of young for future tracking. Other nests are surveyed from a distance using optics or cameras with telephoto lenses, a mirror, smartphone or GoPro on an extension pole and a sUAS (when operated by a FAA licensed unmanned pilot). The goal is to recorded the total number of nesting pairs throughout the State.

Union County Falcons Thrive in Urban Ecosystem

Kathy Clark carefully places a young falcon in a reusable shopping bag.

On May 23, NJDEP Fish & Wildlife Supervisory Zoologist Kathy Clark and myself visited the Union County Courthouse in Elizabeth, NJ to band the three eyases that were produced by the nesting pair of peregrine falcons. We were joined by Union County staff and guests, who assisted with the banding. The nest is located on the roof of the building. As soon as the hatch made a sound, the adults took off and started to defend their nest and flightless young. As we enter their turf, we are dive bombed by the adults — it is clear that the female has become more aggressive — as she flies very close to us on the roof in sweeping dive bomb attacks. As Kathy goes to the nest to grab each young who are placed in reusable shopping bags, I use her trusty feather duster to ward off the adult female. All who enter the roof wear fall arrest harnesses and hard hats. Kathy and I know that the hard hats are not just worn for fall protection, but also from attacks from above. Both of us received bumps from the adult female to our helmets!

Three healthy peregrine falcon eyases in Elizabeth!

Saturday, May 7th, 2022

by Ben Wurst, Habitat Program Manager

Another season of growth and new life is here! As many species are beginning their annual life cycle to reproduce, some peregrine falcon pairs already have young. The eyases (young falcons) at the Union County Falcon Cam are a prime example. They are now a little over a week old and have been examined and treated for a pigeon borne disease, called trichomoniasis, which adult falcons can transfer to their young. If young falcons would get trich., then they could perish. Kathy Clark, NJDEP Fish & Wildlife Supervisory Zoologist, UC staff and colleague Cathy Malok, w/ The Raptor Trust visited the site to ensure the survival of this brood.
