CWF’s “Howls for Owls” event at Screamin’ Hill Brewery in Cream Ridge, New Jersey was certainly among our most fun fall activities. Owl enthusiasts flocked to this 170-acre farm for an evening of family-friendly activities in celebration of barn owls. Children and adults alike enjoyed dissecting owl pellets, creating owl masks, making adorable pinecone owls, and participating in three rounds of owl-themed trivia. Many attendees even came dressed in owl costumes!

Activities were designed to be fun and to teach attendees about owl adaptations. Owl pellet dissection was one of the most popular things to do. Children and their parents often worked together to extract all the bones found within a pellet and figure out what the owl had consumed.

Kids also made special owl masks with tubes around the eyes to mimic the oblong shape of an owl’s eye. Owl eyes are fixed in place and shaped more like a doorknob or tube than a sphere. When the mask is on, kids discover that they can only see in front of them and must rotate their heads around to look from side to side- just like an owl. Because owls cannot move their eyes, they are adapted to turn their head about 270 degrees around!

“Howls for Owls” had activities for everyone! Crafts, trivia, owl pellet dissection, and other activities kept visitors busy.

This marked the second year that CWF worked in close partnership with New Jersey Fish and Wildlife and Edwin B. Forsythe National Wildlife Refuge (EBF) to monitor and manage birds on Horseshoe Island. The island, located just offshore on the southern edge of the Little Egg Inlet, has quickly become one of the most important sites for beach nesting birds in the state, as well as a critical resting and feeding site for migratory shorebirds.

Horseshoe Island hosted the state’s largest black skimmer (state endangered) colony this year with just over 1400 total adults or about 700 pairs. Although flooding and some avian predators impacted the overall nesting success at the island, at least 225 skimmer chicks “fledged” from the site. Horseshoe’s skimmer fledglings, along with those from nearby Holgate, a unit of EBF, and especially from Stone Harbor Point in Cape May County, made 2023 a moderately good productivity year for black skimmers in New Jersey.

Etiquette tells us that we shouldn’t have a favorite child. I sometimes wonder if the same rules apply to biologists with regard to our study species. If so, my manners fall woefully short, at least where reptiles are concerned.

Conserve Wildlife Foundation has been partnering with the United States Fish and Wildlife Service (USFWS) on bog turtle conservation initiatives for years. We do this using a multi-faceted approach. We connect landowners with qualifying habitat with federal funding opportunities and technical support that can preserve and restore significant wetlands. We assist the state and nonprofit partners with visual surveys to better understand the status of historic populations. Finally, we suit up with USFWS personnel each fall and winter to remove invasive species and woody vegetation that are shading out nesting spots, rendering bogs and fens inhospitable to turtles. We applied to continue this work for the next few years but decided to shake things up a bit by adding in tasks targeting the protection of the bog turtle’s closest living relative… the wood turtle, a state threatened species that is currently under consideration for federal listing.

Restoring floodplains and protecting urban communities may not sound like a typical workday for the biologists of Conserve Wildlife Foundation of NJ (CWFNJ). However, multiple staff and board members of CWFNJ were present at the annual Blue Acres Floodplain Restoration Fall Planting and Clean-up Day on October 27^th, clearing weeds, trash and planting new trees and shrubs at the Tremley Point restoration site in Linden. Blue Acres, a program created by the New Jersey Department of Environmental Protection, helps residents in low-lying areas that are subject to repeated flooding by buying out their properties and aiding in homeowner relocation. The acquired properties eventually become buffer zones, such as floodplains, that protect surrounding communities from the impact of storms and rising sea levels by acting as natural floodwater storage. The land purchased through the Blue Acres program may also be restored into functional wetlands, habitat for wildlife and open green space for the community to enjoy. Blue Acres not only provides disaster relief for residents whose homes have been destroyed or damaged by flooding and surges caused by large storms, but also contributes to the NJ Climate Change Resilience Strategy by proactively creating wetlands and floodplains to lessen the severity of future flood events.

by Meaghan Lyon, Wildlife Biologist

Internationally celebrated, Bat Week runs from October 24^th through October 31^st. This week we celebrate bats to raise awareness for these nocturnal creatures that are often left in the dark. In New Jersey, we have two federally listed bat species, the Indiana bat and the Northern long-eared bat. Several more bats are being uplisted to the threatened and endangered list. Threats primarily include habitat loss and a fungal disease called white-nose syndrome.

2023 JB McGuire Grassland Bird Survey

Posted on October 13, 2023 by Rachel McGovern

by Meaghan Lyon, Wildlife Biologist

Each year since 2017, CWF has been teaming up with partners from the USFWS New Jersey Field Office to survey the JB McGuire Airfield for grassland birds during the breeding season. Part of a long-term monitoring project, the airfield has been undergoing habitat restoration to maintain native warm season grassland habitat. The habitat restoration efforts are nearly 70% complete with roughly 700 acres seeded since 2017 and another 100 acres to be completed the following year.

Six of the ground-nesting bird species documented at the airfield are State-listed as either endangered, threatened, or of special concern. The eastern meadowlark (Sternella magna), a member of the blackbird family, is a State Species of Concern. It prefers a minimum of ten to twenty acres of unfragmented dense grasses of medium height for nesting. The State-threatened grasshopper sparrow (Ammodramus savannarum) favors patches over 100 acres containing short- to medium-height bunch grasses interspersed with patches of bare ground, a shallow litter layer and scattered forbs. The savannah sparrow (Passerculus sandwichensis), also State-threatened, requires a mix of short and tall grasses, a thick litter layer, dense ground vegetation, and scattered forbs. Another member of the blackbird family is the State-threatened bobolink (Dolichonyx oryzivorus). Bobolinks prefer to place their nests in areas of greatest vegetative height and density and could potentially nest in patches as small as five to ten acres. The State-threatened horned lark (Erimophila alpestrias) nests in areas of barren ground with short and sparse cover and are quick to abandon sites as vegetation grows thicker.

CWF had a busy summer at the Long Beach Island Foundation of the Arts and Sciences (LBIF), having launched a new partnership this year to help strengthen their science programming through a grant from the Osprey Foundation. A number of offerings targeting both adults and kids, highlighted by three week-long science camps for ages 7-9 and 10-12, were developed and led by CWF’s staff. The LBIF facility, with its close proximity to both the ocean and bay, is an ideal location to feature New Jersey’s coastal species and their unique conservation challenges.

The Complicated History of Our Marshes and an Update on Restoration Progress

Posted on August 23, 2023 by Rachel McGovern

by Caroline Abramowitz, CWF Biological Technician

When looking at the expansive mudflats along the marshes of the Delaware Bay, it is hard to imagine that the area was once densely vegetated and home to a variety of bird species. This spring, CWF began work on a new marsh restoration project funded by the National Fish and Wildlife Foundation and led by Ducks Unlimited and the U.S. Fish and Wildlife Service (USFWS). CWF was contracted to assist with biological monitoring at sites targeted for marsh restoration along New Jersey’s side of the Delaware Bay. Restoration efforts for our sites are being directed toward mudflats that exist due to significant physical alterations made to the marsh in the past. The story of how these mudflats came to be lies in the area’s history and roots in salt hay farming.

As early as 1675, settlers arriving on the Delaware Bay built dikes in salt marshes to protect land from saltwater inflow and create an environment more conducive to salt hay farming and development. One of the most important types of salt hay harvested along the Delaware Bay was Spartina patens, a crop that was widely used as bedding and feed for livestock due to its high nutritional value. By the mid-1800s, at least 14,000 acres of marsh were impounded in Salem County alone with comparable areas altered in both Cumberland and Cape May counties (Cook, 1870). Impoundments restricted tidal flow within the marsh, which stopped the natural process of marsh accretion in which sediment is consistently added to the marsh to increase its elevation. Additionally, drier conditions exposed marsh soil to too much air, resulting in the breakdown of soil and further loss of elevation.

Collaborative Projects Gather Data About Bats in the Garden State

Posted on August 18, 2023 by Rachel McGovern

by Leah Wells, Assistant Wildlife Biologist

Conserve Wildlife Foundation of New Jersey (CWF) works hard every summer to protect New Jersey’s bats by employing continuous research, education and outreach endeavors. Our Summer Bat Count project and Mobile Acoustic Surveys, both in collaboration with the State’s Endangered and Nongame Species Program (ENSP), are essential components of these efforts, enabling us to gather and document crucial information about bat populations within the state.

Since 2003, the Summer Bat Count project has relied upon the commitment of dedicated volunteers. Equipped with only a fresh set of eyes, these volunteers tally bat populations at known summer roost sites, whether it be a bat house, attic, bridge or church. The project’s primary goal is to gain a deeper insight into the distribution of bats across the state, their preferred roosting conditions and the fluctuations in population over time. While the outcomes of this year’s survey are still pending, emergence surveys during the 2022 maternity season revealed a noteworthy increase in bats for a particular roost in Warren County. This roost has been consistently monitored, with data dating back before the introduction of White-nose Syndrome.
