Tree Mob™!: Migration Magic


Robert Mayer, Arnold Arboretum Docent

1 Session: Thursday, November 1,12:15pm
Location: Meet on Bussey Hill Road by Acc. # 125-35*A


Visit Albizia julibrissin (silk tree or mimosa) with the Arnold Arboretum’s resident birder Bob Mayer to learn about some of the avian migrants who feed in this arboreal oasis on their travels, either north or south. You will likely see blackpoll warblers, yellow-rumped warblers, ruby-crowned kinglets, and more. Even a Cape May warbler is a slight possibility, as one was sighted recently in this tree. Join us to learn why these birds have chosen this particular tree. Meet at Accession 125-35*A on Bussey Hill Road, opposite the entrance to the Explorers Garden at 12:15pm on Thusday, November 1. Bring binoculars if you have a pair.

What’s a Tree Mob™?

Tree Mobs are interactions with scientists or other specialists at the Arnold Arboretum, and provide another pathway to enjoy and learn in the landscape. Experts share little-known facts about our living plant collection, its relevance today, and its importance to future generations. A Tree Mob may attract a small group or a large gathering—we won’t know until it takes place. Join us in the landscape and discover something new.

What can I expect?

Plan to spend approximately 30 minutes learning about an interesting component of our collection. You can then continue your exploration of the Arnold Arboretum on your own. Tree Mobs are time, date, and location specific.

How does it work?

We will communicate about Tree Mobs by various means (see below). Using mobile technologies, such as a smartphone with location-awareness enabled, you will be able to navigate to the event location. You can also view and print a map we will provide with the day’s Tree Mob location on our website. With directions in hand, proceed to the designated meeting place to participate in our experiment for spontaneous learning.
