Bird Calls on Radio

Italy

Preliminary experimental shortwave broadcasting in Italy began in the mid 1920s with the use of two low powered communication transmitters near Rome with the callsigns IAX and IAY.  Under the direction of their own legendary radio pioneer, Guglielmo Marconi, a shortwave broadcasting station was developed at Prato Smeraldo, again just outside Rome, and a little to the south.

Two shortwave transmitters at 25 kW each were installed and these were officially opened on July 1, 1930 as 2RO.  Four years later again (1934), two more similar transmitters were installed at the Prato Smeraldo Shortwave Station.  However all shortwave transmissions were discontinued on October 1, 2007, at the end of its illustrious broadcasting history extending over more than 80 years.

At the sign on for each shortwave transmission RAI played the delightful sound of a bird followed by their theme music.  It is suggested that the Bird Call as heard from the RAI shortwave service is from their national bird, the Italian Sparrow.

Iraq

There are two stories about the Bird Signal from Radio Baghdad.  One story states that the German government gave a gift to the royal family in Iraq in 1936, and that gift was a mechanical singing bird which is on display in the Iraqi Media Museum in Baghdad.  Back then, a recording of that unique bird signal was then introduced as the tuning signal for the sign on routine of Radio Baghdad.

The second story states that when Radio Baghdad was inaugurated back on July 1, 1936, the call of a live Bulbul Bird was broadcast for five minutes each morning as the opening tuning signal.

However after the Bulbul Bird died, the king granted Bagdad Radio the use of a mechanical Bulbul Bird that he had previously bought in London.  The Bulbul Bird is better known as the Nightingale.

The first shortwave tests in Iraq were carried out by an English Air Force officer in 1924.  Then in 1940, the government of Iraq opened a new 5 kW shortwave station at Baghdad during the year 1940.  That station identified on air under several callsigns, such as  HNE, HNK, and HNI, depending upon which frequency was in use.

Zambia

The African nation of Zambia was identified in colonial times as Northern Rhodesia, and it adopted its more recent designation as Zambia in 1964.  The first shortwave program service in what was then Northern Rhodesia was broadcast in 1946 from an already established communication station that was on the air in Lusaka under the callsign ZQP.  Back then station ZQP operated with 500 watts on 7220 kHz and Initial programming was a brief daily service that was taken on relay from the radio station in (Southern) Rhodesia at Salisbury.

The squawking Bird Call that has been heard as the opening tuning signal from Radio Zambia on shortwave seems to be the African Fish Eagle, which is the national bird for three African nations; South Sudan, Zimbabwe (Southern Rhodesia) and Zambia.

Nauru

The island of Nauru is just a small almost circular island of 8 square miles and it lies in the Pacific area of Micronesia, nearly three thousand miles northeast from Australia.  For more than a hundred years, Nauru has featured prominently in wireless and radio history.  There has never been a shortwave broadcasting service from Nauru, though there have been many occasions when international shortwave has achieved necessary communication with other distant countries.  The  Coastal Radio Station VKT for example was often in shortwave communication with VIS in Sydney Australia.

There is a government operated FM station on Nauru, and there was a time when this station signed on each morning with the sound of a bird call.  That bird was the Nauruan Canary.

New Caledonia

The French island of New Caledonia lies about 750 miles off the east coast of Australia.  A major shortwave station at St. Marie on New Caledonia was taken into service in 1968.  Even though that shortwave service from New Caledonia RFO was intended mainly for their home islands and for the other French islands in the Pacific, yet they were heard regularly with good signals in both New Zealand and Australia.  That RFO shortwave service was on the air for a little over a quarter of a century and it was finally closed forever in 1994.

The shortwave service from RFO in New Caledonia had adopted a bird call as part of their daily sign on routine.  That bird was the Kagu, an almost flightless forest bird found only in New Caledonia.
