The Clifton Institute is starting a research project to study box turtles. They want to know what habitats they use, what time of year they’re most active, how big their territories are and how much overlap neighboring territories have, and most importantly what can be done to help conserve this long-lived species. To start, they need to have a better idea of how many box turtles there are on their property and where they can find them.  The Clifton Institute needs your help! In late May or early June, they are going to wait for rainy weather and spend a day walking all of the trails looking for box turtles. They will divide registrants into teams to cover more ground. The more eyes the better! No experience is needed. Volunteers will be walking on uneven and potentially steep trails.

They chose May 18 as the date they expect to be the earliest possible survey date, but they will wait for the right weather and email registrants with more information.

Warbler Song Bootcamp: Hybrid webinar, April 15th

Friday, April 15, 2022
6 – 7 pm
Register here for either in person or online.

Brush up on your warbler songs just before the migrants arrive in droves. Sponsored by The Clifton Institute, they will listen to the songs of each of the migratory warblers that pass through our region in spring, while looking at spectrograms to help visual learners identify differences in similar songs. They will also briefly discuss habitats where breeding warblers can be found in our area and cover a handful of other migrants such as vireos and thrushes.

This workshop will be of interest to birdwatchers of all skill levels. It will definitely be more fun than listening to a warbler song CD in your car! This program will be a hybrid in-person / virtual event. They think it’s more fun to get together in-person and learn from each others’ birdwatching experience, but also want to make this class accessible to people who don’t live within driving distance of the Clifton Institute. Please indicate which way you plan to attend below by RSVP’ing. If you RSVP to the “Virtual (Online) Only”, you will be sent a Zoom link a few days prior to the event.

Learn how to identify warblers visiting Northern Virginia in spring migration during this Audubon Society of Northern Virginia course.

Warblers are some of the most challenging birds to identify. They are small and often fast-moving, with easily confused calls and songs. This four-part course will cover plumage, behavior, and vocalizations to help you identify the 35 species of warblers you might see this spring.

This course will be presented by Bill Young, co-creator of the website, which describes the natural history of Monticello Park, a hidden gem and warbler hotspot in Alexandria, VA. Bill is the author of the book “The Fascination of Birds: From the Albatross to the Yellowthroat.” He also makes nature videos, and his YouTube channel has had 850,000 views.

An optional field trip, led by Phil Silas, will be held on Sunday, April 24, 2022 at 7:30 AM for 20 Identifying Warblers participants. The field trip fee is an additional $25 for members, $35 for nonmembers. The field trip will be held in Woodbridge, VA, but the exact location will only be revealed after registration. An email with a link to register for the field trip will be sent upon registration for Identifying Warblers. The field trip is first come, first serve and there will be a waitlist.
