OLD WORLD SPARROWS Passeridae
- 40 species native to Eurasian and Africa
- DR personal total: 28 species (70%), 8 photo'd
Old World Sparrows [Passeridae] are familiar to most people, even those
who are non-birders, because some of them are ubiquitous urban
sparrows. Two species [House Sparrow, Eurasian Tree Sparrow] have been
introduced to non-native urban habitats almost worldwide. I also think
of them as birds of cold and blustery high elevations across Eurasia
(i.e., snowfinches). Yet there are just as many species in Africa as
anywhere else, and this sometimes comes as a surprise. This one (left)
is the colorful Cape Sparrow, common in Cape Town and
present in a wide range in southern Africa. The uniquely urban style of
'barbed wire' on which this one sits does suggest the commensal nature
of genus Passer. Most of the species in the Passeridae are in the genus Passer (27 species, 68%).
is hard to say which is the most familiar of all Old World Sparrows,
but if you live in North America, where none are native, it is the House Sparrow
(right; a black-bibbed male is shown). Native to the Holarctic, it is
"introduced and thriving" in urban North and South America; in southern
Africa; in eastern Australia; in the Bahamas, Azores, and Cape Verde
islands; and in Tasmania, New Caledonia, New Zealand, Hawaii, and
Easter Island, among others (Clement et al. 1993). Considered a 'pest'
species in many agricultural areas for feeding on grain much of the
year, it may actually be beneficial to farmers because of the number of
pest insects and larvae that it feeds to its many young (Summer-Smith
2009). Where weather permits it has two or three broods each year. It
is been one of the most extensively studied bird species on earth, with
over 4800 entries in a recent "bibliography of the genus Passer" (Lowther & Cink 1992).
The other globally widespread member genus Passer is Eurasian Tree Sparrow
(left and below). This adaptable species occurs from sea-level (left, a
photo from Sulawesi, where it was introduced) to high elevations. The
nest-building bird below was at nearly 12,000' elevation (3600m in
Eurasian Tree Sparrow has been widely introduced to non-native lands —
including the Eastern Ghats, India; Sulawesi and many islands in the
Lesser Sundas; Philippines; southeast Australia; Micronesia; Hong Kong
and Singapore — these introductions do not always thrive. Introductions
to Bermuda, the Andaman Islands, and New Zealand in the 19th century
were unsuccessful, probably owing to competition with introduced House
Sparrows (Clement et al. 1993). An introduced population around St.
Louis, Missouri, and adjacent Illinois and Kentucky, still exists and
vagrants have appeared at some distance, but it is not taken off and
expanded to much of temperate North America as has House Sparrow.
There are many more localized sparrows in genus Passer, but most of them are commensals with humans to some extent (17 of 27 per Summers-Smith 2009). The Plain-backed Sparrow
of southeast Asia (right) is more rural than Eurasian Tree Sparrow, and
is localized in occurrence, but still prefers man-altered habitats such
as agricultural areas or the edges of villages.
In southern Europe, House Sparrow and Spanish Sparrow P. hispaniolensis interbreed where ranges meet, the hybrid zones are comparatively narrow. The taxa called Italian Sparrow P. italiae was recently been widely accepted at species level despite a degree of interbreeding.
In Africa there are a series of Passer
sparrows adapted to open country and away from heavy forest. Recent
studies have split populations of what was once the widespread
Gray-headed Sparrow P. griseus (now Northern Gray-headed Sparrow) which have a range of bill sizes all the way up to bulbous bill of Parrot-billed Sparrow P. gongonensis. The prior Rufous Sparrow P. motitensis (now Great Rufous Sparrow) is split into four species.
The Passeridae also includes five species of Petronia (genus Petronia, sometimes called "rock sparrows"), that are generally small, drab birds of (often) rocky and arid habitats. An example is Rock Petronia
(above left); it has a wide range from southern Europe and northwest
Africa across the Middle East to high elevations in eastern China.
The other important group in the family are the snowfinches (genus Montifringilla).
These are high-elevation species adapted to snow-colored and alpine
habitats in Eurasia. They have sometimes been placed with fringillid
finches in the past, but they are now clearly established as passerids
(e.g., Johansson et al. 2008). White-winged Snowfinch M. nivalis
(called just "Snow Finch" in some European literature) occurs at
glacier edges and alpine habitats in a patchy distribution in montane
Europe to the Tibetan Plateau. The rest of the snowfinches reside in
stony or barren high-elevation plateaus in eastern Asia, from Tibet to
Mongolia. Examples include Pére David's Snowfinch (above right, a very plain female) and Blanford's Snowfinch
(below). In the family group (below) two begging youngsters confront a
nicely-colored male in high stony desert at nearly 12,000' elevation
(6300m) in Qinghai, China.
|It should be mentioned that all other global checklists place the Cinnamon Ibon Hypocryptadius cinnamomeus,
of montane Mindanao, Philippines, in the Passeridae. Using molecular
methods, Fjeldså et al. (2010) shocked the ornithology world by
showing this bird of cloud forests had evolved at the base of the
Passeridae clade. The was shocking as it had traditionally been
considered to be an unusual white-eye among the Zosteropidae. The name
of the paper was "The Cinnamon Ibon Hypocryptadius cinnamomeus
is a forest canopy sparrow," and now "everyone" lists this unique
species among the Old World Sparrows. However, Fjeldså et al.
(2010) opined that the Ibon had diverged from the rest of the
Passeridae about 31 million years ago. This is much older than many
other bird lineages that are now considered worthy of Family level
designation. Perhaps there is reason to wish for substantiation of the
timing of divergence, but for now, consistent with the apparent age of
divergence, I have elevated it at Family level as the Hypocryptadiidae.
Photos: The Cape Sparrow Passer melanurus at Cape Town, South Africa, in March 2007. The male House Sparrow P. domesticus was photographed in Monterey, Calif., USA, where it is an introduced species. The large photo of Eurasian Tree Sparrow P. montanus
is from Sulawesi, Indonesia, on 6 Oct 2011, and the nest-building male
was in the Caka Valley, Qinghai, China, on 20 June 2004. The male Plain-backed Sparrow P. flaveolus was at Pak Thule, Thailand, on 22 Dec 2012. The Rock Petronia Petronia petronia was in the Caka Valley, Qinghai, China, on 20 June 2004. The female Pére David's Snowfinch Montifringilla davidiana was near Qinghai Lake, China, on 17 June 2004, and the male with fledglings Blanford's Snowfinch Montifringilla blanfordi were in the Caka Valley, Qinghai, China, the next day.

Family book: Rating
Clement, P., A. Harris, and J. Davis. 1993. Finches and Sparrows: An Identification Guide. Princeton Univ. Press, Princeton, N. J.
is a rather thick contribution to the bird families of the world
literature, nicely done by Princeton Univ. Press and better than the
"average" recent publication in various other series. The Princeton
Press books generally fall short of the excellent quality of the Oxford
series, in my view. Both of these series use "field guide" style poses
for the artwork, but the Oxford series excels in behavioral information
and in having the leading experts on a family author the books. This
one, however, a solid contribution that covers not only the
Fringillidae, but the Estrildidae (waxbills and allies) and the
Passeridae (Old World sparrows). It does not include the Emberizidae
(New World sparrows and buntings). I have used this book much more
often to check up topics on finches, and really have not seriously
studied it for Passeridae.
Each species has a
fine painting of both sexes (when they differ), details of
identification and plumage, a summary of distribution, and brief
comments on habitat, migration, measurements, and references. The
subtitle "An Identification Guide" seems odd to me, because of
necessity the book cannot delve into state-of-the-art details of
identification, but rather presents a overview of the family throughout
the world. It is actually a "mini-handbook" rather than an i.d. guide.
For example, what this book says about separating Cassin's Finch Haemorhous cassinii and Purple Finch H. purpureus
is accurate enough as generalizations, but there is insufficient space
to detail such things as variation in western Purple Finches which
include streaked undertail coverts (usually considered a feature of
Cassin's) or to emphasize bill shapes. The European birder visiting
America will likely separate the species adequately, but a local birder
searching for a vagrant is as apt to be misled by the text as not. For
this reason — and because of the Eurocentric choices for names (e.g.,
"Trumpeter Finch," unmodified, is a species, but then they use the
modified term "Mongolian Trumpeter Finch" for another species) as well
as some overly conservative taxonomy (e.g., failure to split the
rosy-finches into four species; they lump the three American species
with the Old World "Rosy-Finch") -- I downgrade this decent book from a
"four star" to a "three star" entry.
A fine introduction to the Passeridae, with some excellent photos, is in Summers-Smith (2009).
