Our Office Staff


David Cavill, Controller

David Ian Cavill (please, call him Cavill—rhymes with travel) serves NYC Audubon as controller and has a professional background in non-profit finance, operations, and management. Much of Cavill's connection to mission driven organizations comes from a sense of spiritual motivation. He is currently pursuing rabbinic ordination at the Academy for Jewish Religion, is a graduate of the Jewish Theological Seminary’s undergraduate joint program with Columbia University, and attended Yale Divinity School where he earned the degree of master of divinity.

Cavill currently lives in the Bronx which is the most up and coming of any borough in NYC. He is outdoorsy and enjoys hiking and camping but is also at home on the sofa watching cooking shows and the Netflix catalog. In 2014 Cavill completed a certificate in mixology from the Columbia School of Bartending and is grateful to have a skill to fall back on.

Kathryn Heintz, Executive Director

Kathryn joined NYC Audubon in September 2014. She is eager to advance NYC Audubon’s scientific research, to build its educational work and public programs, and to support its advocacy activities throughout the five boroughs—all efforts that share a common goal of preserving critical natural areas that provide wild birds with welcoming, safe, and healthy habitats. A healthy environment for wild birds is a healthy environment for all New Yorkers.

Raised in suburban Washington, DC, Kathryn learned to love wild birds at the Audubon Naturalist Society’s Woodend Nature Sanctuary in Chevy Chase, Maryland. She has built her professional career in New York City. She served for the past two years as director, principal gifts with the Wildlife Conservation Society, the zoological and global conservation organization headquartered at the Bronx Zoo. From 2001 to 2012 she was director of development at Wave Hill, the public garden and cultural center in the northwest Bronx, following seven years in a similar capacity with the Chamber Music Society of Lincoln Center.

Kathryn studied literature as an undergraduate at SUNY’s Purchase College, and performing arts administration as a graduate student at NYU’s Steinhardt School of Culture, Education, and Human Development.

Kaitlyn Parkins, Conservation Biologist

Originally from Maryland, Kaitlyn grew up with one foot in the rural countryside and another in the urban landscape of Baltimore. This dichotomy has continued to drive her passion for urban ecology and urban wildlife conservation, concepts that to some people seem diametrically opposed. Kaitlyn began her career in the biological sciences by studying native plants, surveying monarch butterflies, assisting with songbird banding, and working in environmental education. In 2011 she moved to New York City to study ecology at Fordham University and completed her Master's degree thesis work on the City’s urban bats. Kaitlyn first came to NYC Audubon in 2013 as an intern focusing on the Project Safe Flight program and she is thrilled to re-join the team as a staff conservation biologist. Her current research interests include animal migration and movement and innovative approaches to creating habitat in urban spaces. In her spare time, Kaitlyn enjoys hiking, photography, making her own clothes, and drinking bird-friendly coffee.

Kaitlyn holds an MS in Biology and an Advanced Certificate in conservation biology from Fordham University and a BA in biology & psychology from McDaniel College.

Debra Kriensky, Research Associate

Debra grew up in the Boston area, and her love of nature and animals started at an early age. Her specific interest in birds, however, came much later in life after trying to identify the species she had seen on a trip to Costa Rica. She has been birding and photographing birds ever since.

After college, Debra spent several years working in the film industry at companies such as Miramax Films and National Geographic Films. All the while, she remained passionate about the environment and in 2012 she decided to pursue a Master's degree in conservation biology. Debra started off as an intern at NYC Audubon through her thesis work on horseshoe crabs and shorebirds in Jamaica Bay. She is excited to be continuing this work and assisting with NYC Audubon's other conservation and research programs as a research associate.

Debra holds a BA in communications from the University of Wisconsin-Madison and a MA in conservation biology from Columbia University.
