The Coastal Barn Owl Project team is gearing up for another round of nest box installations in coastal southern New Jersey. After a successful fundraising appeal, we can now thank our donors by adding more potential nesting opportunities for barn owls, a species in population decline.
Our fourth and most recent box was just installed on October 22 in the saltmarshes of Cape May County. With each install, the team is becoming more efficient, and we hope to get several more boxes up in key locations before early spring when the owls begin their search for suitable nesting sites.

Coverboards are typically placed along ecotones, where species diversity is expected to be greatest. The corrugated tin board, pictured above, was positioned along a forest edge where larger deciduous trees meet a more open, sandy landscape.
How do you survey for animals that spend most of their time hidden under leaf litter or wedged between fallen tree limbs and rocks?
In the case of reptiles and amphibians, the answer is to use coverboards!
Coverboards are materials that are intentionally placed within a potential habitat, often along ecotones (where different habitat types- e.g., wetland and forest, field and forest, etc. come together) that trap moisture and retain heat, creating favorable conditions for our “cold-blooded” (ectothermic) friends. Researchers often arrange coverboards in long transects or arrays and collect data on the diversity of the community underneath the boards as compared to the surrounding environment. This technique was used by NJDEP Division of Fish and Wildlife to survey for herptiles in 17 wildlife management areas in the early 2000s (Golden, 2004). A total of 30 species were recorded during the first year of the study, including long-tailed salamanders, pine barrens tree frogs, and northern pine snakes, all of which are listed as threatened in New Jersey.

This past week I had the pleasure of assisting Supervising Zoologist, Kathy Clark with NJ Fish & Wildlife’s Endangered and Nongame Species Program to install a new nestbox for state endangered peregrine falcons. The new nestbox was installed atop the Sheraton Atlantic City Convention Center Hotel. Peregrine falcons are not new to Atlantic City. They have nested in A.C. since 1987, where the first pair nested on the 23rd floor of the Hilton/Atlantic Club. Since then new pairs have established nests on other tall buildings and structures, like the Hard Rock Casino and A.C. water tower.
The 2021 New Jersey eagle nesting season was another good year for NJ’s eagle population. The final numbers and details will be available in the 2021 Annual Bald Eagle report published in December. There are over 100 eagle project volunteers who monitor eagle nests/s during the season. They are an extremely dedicated group who not only monitor eagle nests but help to protect the nests. Volunteers become familiar with their pairs and get to witness all kinds of eagle (and other wildlife) activity. I asked the volunteers to send me their one favorite photo from this season.
A season of change and hope at the Barnegat Light Osprey Cam.

By far, this was the most viewed season of the Barnegat Light Osprey Cam, with over 360,000 views and 111,000 hours watched! It was a season of change. Viewers throughout the world watched as the mated pair successfully fledged two healthy young. We witnessed the trials and tribulations of a new pair, especially the female, who we believe attempted reproduction for the first time in her life. We saw that life as a young osprey was not always guaranteed, which is something we rarely get to witness but know is quite common at many nests throughout the world; however, with an experienced male and plentiful prey, the surviving young thrived. As we work on a season long highlight video, here is a brief summary of their nesting season.
A couple weeks ago colleagues with NJ Fish & Wildlife shared a video clip of a dark osprey who landed on a nest platform along the Maurice River near Leesburg, NJ. “Looks like an oiled bird” the text read. Indeed it looked like the bird was exposed to some form of petroleum product, which stained its feathers a dark color. At the time, there was no oil spill reported to NJDEP (this was on May 10) and the video shows that the bird was observed on the nest on May 1, 2021.

Just imagine having to defend your home from an invader who wants to steal your home and mate. All you have to protect yourself and home are your bare hands (or talons). You fought this same battle several years ago and staked your claim here. It was a hard won battle that could have been the end.

Humans have played a key role in the recovery and stability of nesting ospreys throughout New Jersey and beyond. Today around 75% of the population, close to 500 pairs, rely on nest platforms designed specifically for them. They provide a stable nest platform, adequate perches, and protection from potential ground predators, aka raccoons. Many platforms are located in very close proximity to people, which make for excellent viewing and educational opportunities. Ospreys are a symbol of a healthy coast and resiliency in a dynamic region.

It’s not very common to see ospreys, a large predatory bird, nest on the ground. Despite the rarity of these sightings, it has become more common and acts as a glimpse into the past (and future), before humans dominated the landscape. Today, more and more ospreys are building nests on the ground and snags over water.
