Why Woodpeckers are Scarce in the North

On the 18th of June 1858, one hundred and sixty years ago today, Darwin claims [1] to have received that fateful letter from Alfred Russel Wallace—probably the most famous letter in the history of science. The original letter was lost but it was transcribed and read to the Linnean Society of London on 1 July …

Audubon’s Legendary Experiments

In his Ornithological Biography [1], John James Audubon describes two experiments that have become legends in the annals of ornithology. Both were ingenious ideas, but Audubon’s conclusions were misleading and remained uncorrected for more than a century. According to  a new paper by Matthew Halley in Archives of Natural History, one of those experiments might …

A Whiskey-Jack by Any Other Name

The year I turned 21, I got my dream job: seasonal naturalist at Algonquin Provincial Park. Algonquin, established in 1893, was only the second provincial park to be created in Canada, and the first to be designated to protect a natural environment [1].  This vast ‘wilderness’ area (7653 km2) is only 3 hours by car …

The Spring Rivalry of Birds

Unless you have been living in a cave for the past couple of months, you will have been well aware of the spectacle of mature, powerful males posturing to one another, showing off their weapons, advertising their prowess, and intimidating their neighbours. Some of them even coerced females into unwanted sexual acts, or spent some …

George Ord’s Warbler

I have always liked the Cape May Warbler. The male in spring is a handsome bird, but scarce enough here in eastern Ontario that I see only one or two every spring [1]. When I first saw one on migration at Long Point Bird Observatory in the 1960s, my friend and mentor David Hussell said …

Lumpers and Splitters

Almost everyone I know who is interested in birds has their favourite group, and the reasons for those favourites vary widely. For some, the difficulty—and their mastery—of field identification is most appealing: I am thinking peeps, LBJ sparrows, fall wood warblers in North America and leaf (Phyloscopus) warblers in Europe. For others, it’s the beauty of—variously—their …

The First Textbook of Ornithology?

Despite their association with school courses, and the ready availability of information online, textbooks have long been—and still are—useful for working ornithologists. The OED says that a textbook is : A book used as a standard work for the study of a particular subject. By that definition, textbooks of ornithology have been with us for almost …

Red Eggs

The cover or frontispiece of almost every book about birds’ eggs is adorned with a picture of a common guillemot (Common Murre [1]) egg. Why? There are several reasons—the common guillemot’s egg is an extraordinary shape, it’s brightly coloured, and the variation in the colour and maculation seems almost infinite. Egg collectors, or oölogists as …

Serendipity 101

The more I read about the history of ornithology, the more it strikes me how important serendipity—blind luck—has been to that history. Ernst Mayr’s career, for example, was a long series of fortunate events. No question that Mayr was brilliant, ambitious and creative, but the goddess of fortune was definitely smiling on him. One hundred …

A Bird’s Eye View

When I started my PhD at McGill University, in 1973, I was thrilled to discover that the university had a library devoted just to ornithology: the Blacker-Wood Library of Zoology and Ornithology. This library was a primarily large room located in the basement of the university’s  immense Redpath Library just down the road from the …
