Glen Mittelhauser

Executive Director and Founder
Areas of Expertise: 
Ornithology, botany, museum curation, database design, statistical analysis, sailing

Glen grew up in Connecticut and spent his summers sailing every moment he could.  He attended College of the Atlantic in Bar Harbor, Maine and graduated in 1989 with a Bachelor of Arts degree in Human Ecology, with a focus in the biological sciences. Since getting his Master of Science degree in Zoology (with a focus on ornithology and statistics) from the University of Maine in 2000, he has served as the managing editor for two regional natural history journals (The Northeastern Naturalist and The Southeastern Naturalist), been appointed external graduate faculty at The University of Maine and served on 3 graduate student committees, and been hired as the project coordinator for the Maine Bird Atlas.  He founded Maine Natural History Observatory in 2003. 

Maggie Fay Barr

Data Management Specialist/Analyst
Areas of Expertise: 
Ecology, large scale dataset handling and manipulations, reports and data summaries, proofing, and long silent walks in the woods


Maggie grew up in Seattle, Washington and spent most of her youth gazing at the mountains in the distance and enjoying fly fishing when she could.  She graduated from the University of Maine, Machias in 1997 with a self-designed Bachelor of Science degree in Environmental Sciences with a concentration in Conservation Biology.  As well, she did some graduate level studies in biology at the University of New Brunswick, Fredericton, CA.  Since then, she has worked in the fields of fisheries, grass roots watershed conservation, environmental non-profits, and education.  After taking a hiatus to raise children, she has worked for the Maine Natural History Observatory since 2010 and has filled a variety of niche job tasks with the organization where she continues to assist their efforts with the Maine Bird Atlas, various database projects, report and summary development and proofing, and, occasionally, field work.

Logan Parker

Areas of Expertise: 
Field Ecology, Wildlife Monitoring Project Design, Volunteer Coordination, Outreach and Education, Development, and Wildlife Photography


Logan Parker is an Ecologist residing in Waldo County, Maine. Logan started the Maine Nightjar Monitoring Project in 2017 and brought the project (and his passion for bird conservation) to MNHO when he joined the team in 2018. Logan is heavily involved in the ongoing Maine Bird Atlas where he both coordinates and participates in the project's special species surveys. When "off the clock", Logan enjoys birding, writing, gardening, and working alongside his wife, Hallee, on their offgrid home in the Maine woods. Logan is also a wildlife photographer and shares photos and field notes through his project, Here In The Wild.

Elliot Johnston

Postdoctoral Research Associate
Areas of Expertise: 
Community ecology & food webs, aquatic ecology (marine and freshwater), ornithology, statistical analysis


Elliot is a community ecologist who is interested in wildlife-habitat relationships and species interactions, and, ultimately, how this information can shape effective conservation actions. He completed his PhD in Ecology and Environmental Science at the University of Maine in 2023, and he is excited to continue developing coastal research projects at MNHO. During graduate school, his research included examining the effects of commercial seaweed harvest on intertidal birds, describing the winter diet of Purple Sandpipers, and assessing the drivers of inter-pond movements in an amphibian population. Elliot resides in Bangor with his wife, Alice, and is an avid trail runner and sea kayaker.

Celeste Mittelhauser

Database Administrator and Outreach Coordinator
Areas of Expertise: 
Database design, web development


Celeste graduated from the University of Southern Maine in 2019 with a Bachelor’s degree in Music.  Since joining the staff of MNHO in 2013, she has designed numerous relational databases, created graphics and data visualizations, and handled website development.  When not doing graphic design or learning new programming languages, Celeste spends her time studying voice and piano or walking in the woods. 

Finn O'Connor

Areas of Expertise: 
Areas of expertise: Botany, ecology, data visualization & analysis, and having fun falling over in wetlands


Finn graduated from College of the Atlantic in 2024 with a BA in Human Ecology (with a focus on botany, community ecology, and visual arts). Since starting at COA, he has worked on inland and coastal wetland assessments, studied habitat/seabird colony interactions on Maine islands, field assisted on a handful of long-term forest monitoring projects, and staffed the college’s herbarium. He is currently taking time off between his undergraduate degree and a graduate degree to get more field experience, explore, and (theoretically) to rest. When not in the field, he is generally found outside regardless, whether gardening, hiking, canoeing, or making art.
