“Stuart is a very experienced and highly technically proficient field ornithologist. He has particular expertise in onshore and offshore bird survey work, but is also a very experienced field ecologist with knowledge of many species groups. Stuart’s other strengths include his ability to strike up easy friendships with landowners and other fieldworkers, his reliability and the presentation of his work, which is excellent. I have Stuart on numerous jobs over the past 10 years, and he has always delivered an excellent service.”

“Micky is a highly skilled field ornithologist and general ecologist, and also has a well-developed interest in upland plant communities. He stands out from many other freelancers due to his analytical approach to survey work and his attention to detail. As a result, where changes or tweaks to survey are needed to ensure a better end result for the client, he can be relied upon to identify them. Micky is also very conscientious, works well as one of a team of surveyors or as a survey co-ordinator, and is very straightforward to deal with.”

Owain Gabb, Director, BSG Ecology.

“It’s important when commissioning marine surveys that you can trust the data you get back. Micky Maher and Stuart Thomas are among the most experienced and accurate ESAS surveyors in Europe. This is why I looked to them to take part in seabird and cetacean monitoring surveys during my time at JNCC as Seabird and Cetacean Monitoring Ecologist.”
