Almost every Rusty Blackbird that I see in the eastern United States is in flight, so the simple trick is to look up. In order to do that you need to know what to look for: I use sound to know when to look, then look for flying blackbirds that are solitary or in small groups, with long wings and long, club-shaped tails.

Use your ears
First, listen for a slightly different call. All of the blackbirds and grackles give a low harsh check or tuk call in flight. In Red-winged Blackbird this is a relatively simple and unmusical chek, like hitting two twigs together. Rusty Blackbird’s call is more like chook, it has more complexity and depth. Rusty’s call is slightly longer, slightly descending, and with a bit of musical tone. It reminds me vaguely of the harsh chig call of Red-bellied Woodpecker.

With the publication of the revised edition of Hawks in Flight, I wanted to post a little bit about my drawing technique with pen and ink.
Gray Hawk, drawn for the revised edition of Hawks in Flight. The pale color of this species requires a lighter touch, with sparse fine lines, and in pen-and-ink there is little room for error. If you put on too much ink there is no way to take it back.
African Elephant, my first paid job as an artist, drawn for a travel brochure in about 1978.
I’ve always enjoyed black-and-white drawing. I remember being in third grade and spending hours looking at Earl Poole’s ink drawings in James Bond’s “Birds of the West Indies”. A few years later I was enthralled by the simplicity and grace of George Sutton’s drawings in “Fundamentals of Ornithology”.
Ink was my favorite “formal” medium from my childhood through my late-20s when I started doing a lot more painting. My first paid job as an artist was doing drawings for travel brochures, like the elephant shown above (drawn from photographs when I was about 17) and all of my early published art was pen-and-ink drawings.

Spoon-billed Sandpiper. Original gouache painting copyright David Sibley.
Join me on a WINGS/Heritage Expeditions cruise 21 June to 4 July 2013 to search for nesting Spoon-billed Sandpipers in Siberia.
I’ve always been fascinated by Siberia. Growing up in the lower 48 states I dreamed of seeing birds like Steller’s Sea-Eagle, Siberian Rubythroat, even Middendorff’s Grasshopper-Warbler, and the crowning jewel of the Siberian specialties was Spoon-billed Sandpiper. My fascination increased as the population of Spoon-billed Sandpiper declined, and in Feb 2010 I made a trip to Thailand where I could see a few individuals on the wintering grounds. That trip was very successful, and I learned a lot about identification and behavior of the species.
I really wanted to see them on the breeding grounds, but at that time there was simply no practical way of getting to the right locations. Since 2011, however, Heritage Expeditions along with BirdLife International has offered a cruise designed specifically to see Spoon-billed Sandpiper in summer, and I am thrilled to have the opportunity to go along in 2013, which is the last year they plan to run this trip.

Here are three more “flocks” of lentils that need to be estimated. If you need an extra challenge, give yourself a time limit to come up with each number.

The quiz below shows four photographs of the leafy crowns of trees, as you might see them while looking for birds through binoculars or telescopes. Differences in leaf “posture”, arrangement, and color are just as obvious as differences in leaf shape, and all of these species are readily distinguishable at a glance, even in silhouette.
Just like beginning birdwatching, you can start by learning to recognize a few common and distinctive species of trees that you see every day, and as those become familiar you will add more species to your “repertoire”.
These photos were all taken with a Canon digital camera held to a Swarovski telescope at The Nature Conservancy’s Mashomack Preserve, Shelter Island, New York, on 27 August 2012.

Most Passerines only hold juvenal plumage for a few weeks, quickly molting to a more adult-like plumage soon after they fledge and before fall migration. It’s a plumage that is seen almost entirely on the breeding grounds, but the breeding grounds (and fledging time) of many birds overlaps broadly with the fall migration of others, so it’s common to see a mixture of juveniles and fall migrants of various species. Learning to recognize juvenile songbirds, and appreciating the things they all have in common, can help avoid confusion in the late summer and early fall.

This time the answers are arranged randomly, instead of sequentially, and I think this makes it a little harder, since it’s harder to use the range of possible answers as a clue. Suggestions are always welcome.
