Something to Crow About?
This posting is about a news item from Tokyo, Japan. It seems that the local Crows are causing something of a problem.
The Times June 15, 2006 Crows hack into internest
TOKYO’S futuristic image as the world’s most technologically advanced broadband internet-enabled city is under attack from a vicious but decidedly low-tech foe: urban-dwelling jungle crows.Their destructive and unpredictable behaviour during the annual May to June mating season is always highly problematic for the Japanese capital. But this year the aggressive ink-black birds have created a new headache by developing a seemingly insatiable taste for fibre-optic internet cable.
Tokyo has become a victim of its own rush to go broadband. In the past six weeks, hundreds of homes and offices have reportedly been left without high-speed internet service after the crows discovered that broadband cable can be pecked into usable strips more easily than power cables or telephone copper wire ever could. Crows have discovered that the broadband cables, which are strung from telegraph poles across Tokyo, are the perfect consistency for building nests.

Bird Photos on the Net
From time to time I spend time surfing the net for photos of birds from different parts of the world. Numeriscopages is a site from France. It includes beautiful photos of birds, insects, butterflies, animals and flowers. It’s worth spending a few minutes looking at this extensive site. Warning: the site is in French, but there is minimal text to worry about. The photos speak for themselves.

Great Birding Moments #5 Crested Pigeon
Earlier this week while driving to the post office to post some letters, I saw about a dozen Crested Pigeons Ocyphaps lophotes sitting on a powerline. This is a relatively common sight here in my home town of Murray Bridge in South Australia. I have seen loose flocks of 20-30 sitting in rows on power lines or on fences. On several occasions I have counted over 40, with 48 being the highest number in one spot.
Resident Breeding Species
The Crested Pigeon is a resident breeding species in our garden on our five acre block of land on the outskirts of Murray Bridge South Australia. On one occasion a pair nested only five metres from our house, in full view from the sun room where we often eat or sit and read or entertain visitors. The nest is a flimsy platform of small twigs. It is amazing how this poor excuse for a nest holds the eggs, let alone contain several growing chicks. But it is simply palatial compared to another common species around here. The nest of the Common Bronzewing Pigeon has so few twigs that I have been able to stand underneath one and count the eggs!
A bird on the move
The Crested Pigeon historically has been a species of the inland parts of Australia. In recent decades, however, it has spread steadily due in part to the increased availability of water on farms. It is very common in the parks and gardens of Adelaide and is increasingly reported in the metropolitan areas of Melbourne. In southern South Australia it was rarely seen in the south east districts, but I have seen it only a few kilometres from the coast near Mt Gambier.
Habitat
It has been a bird of the rural areas of Australia, inhabiting grasslands, pastures, cropping areas, roadsides and farmyards. More recently it has become common in parks and gardens, golf and race courses, sporting grounds and other urban areas, even in our larger cities.
Common Name
I grew up in the Murray Mallee farming district in South Australia. Throughout this area – and in many other parts of Australia, this species is still called a Topknot, noting its erect crest. This confuses it with the Topknot Pigeon of the rainforests and woodlands of eastern Australia.
I must admit that this is one of my favourite species. It seems such an endearing bird and will allow a close approach to within a few metres if done without sudden movements, especially at the nest (which I try to avoid doing too often). Up close, with the sun on the feathers, one can fully appreciate the stunning beauty of the iridescent colours on the wings.
Twitching in Australia
Twitching of birds is alive and well in Australia. A few days ago someone reported the first ever sighting in Australia of a Grey Headed Lapwing. A report today estimates that over 60 birders have so far been to see this bird at Burren Junction in northern New South Wales. Now this number is tiny when compared to twitching in the USA or the UK where literally thousands of birders descend on the location of rare birds. But considering the vast size of Australia and its small population, this is probably the most twitched bird in Australian birding history with many more birders likely to visit over the coming weekend.
And that is amazing considering that it is in a rather remote location. To get there would take many hours of driving from any of the capital cities. At least 4 hours from Brisbane or Sydney, possibly 10-12 hours from Melbourne and 15 hours from Adelaide. These are very, very rough estimates just to give some idea of the effort some Aussie birders put in just to see one bird.
