posted May 11th, 2012; last edited May 11th, 2012 –– David Sibley I’ve been neglecting trees in my posts recently, but here in Massachusetts spring is the best time of year for tree-watching, and today the sun was out offering some good photo opportunities. Five species of trees in Concord, MA, click to enlarge, and read below for identification; 11 May 2012. photo copyright David Sibley. [...] posted February 26th, 2011; last edited February 26th, 2011 –– David Sibley One of my main goals in creating the Sibley Guide to Trees was to apply modern methods of bird study to tree identification. This meant looking at trees at a distance and trying to figure out what, if any, differences would allow me to distinguish species quickly and reliably in just a glance. I continue [...] posted April 13th, 2010; last edited April 13th, 2010 –– David Sibley Spring is always an exciting time for birdwatchers, as migrants pass through and summer residents return, all in their flashy breeding plumage. This time of year is equally interesting for tree-watching, and it is the best time of year for identifying trees from a distance by their color. Three species of maples, along with [...] posted March 30th, 2010; last edited April 8th, 2010 –– David Sibley In The Sibley Guide to Trees I refer to some species of trees as having leaves (or needles) two-ranked, and several readers have asked me to clarify the meaning of the term. In the introduction of the guide on p. xxix the term is mentioned and illustrated with one example: American Elm has leaves two-ranked, [...] posted March 1st, 2010; last edited March 31st, 2010 –– David Sibley Sugar Maple. Acrylic painting copyright David Sibley. Here’s an opportunity to own a piece of my original art. I have donated an original acrylic painting of the leaf and fruit of Sugar Maple to Mass Audubon’s Ipswich River Wildlife Sactuary in Topsfield, MA. The piece will be part of the silent auction at their [...] posted January 19th, 2010; last edited April 8th, 2010 –– David Sibley I’ve just posted a new page that lists some of my most-frequently-used online references about trees. You can find it here, and it is also linked on the Tree Info page. posted November 30th, 2009; last edited April 9th, 2010 –– David Sibley Thanks to an email from Ray Telfair I’ve taken a closer look at the illustrations and descriptions of hickory nuts on pages 143 to 149 in the Guide to Trees. I used the terms “angled” and “ribbed” interchangeably, and illustrations such as Pignut Hickory p 145 appear “angled”, which is confusing and incorrect, so I’ll [...] posted November 24th, 2009; last edited November 25th, 2009 –– David Sibley Watching the changing colors of fall leaves is always interesting, and even more so when you recognize the species of trees and begin to understand some of the finer points of variation in color. In these four photographs of Red Maple, all taken within a few days in Massachusetts and New Hampshire, I’ll describe a [...] posted November 10th, 2009; last edited January 28th, 2011 –– David Sibley Through this fall I’ve been talking about what I tried to accomplish in my new Guide to Trees. In essence, I tried to approach tree identification in the same way that modern birders approach bird identification, to create “a tree guide for birdwatchers”. Most guides to tree identification use keys at some level, which are [...] posted November 9th, 2009; last edited December 9th, 2009 –– David Sibley In fall it is the bright red and yellow colors of the broadleaf trees that get all the attention from “leaf-peepers”. Much more subtle and largely unnoticed are the changing colors of the conifers. Even though pines and cypresses are evergreen, they still drop some of their leaves each fall. Eastern White Pine twig [...] |
