|Q11. Would you like to share a story about House Sparrows from this time period?||I have got the information from internet
may this contribution may help
For decades a great variety of living beings have been used by men in order to detect possible changes in ecosystems. From lichens, sensitive to pollution for accumulating toxic substances in their tissues, to the birds living in our gardens and buildings, a great variety of organisms have been used as warning signs of the health of the human environment. Moreover trends in numbers over time are of particular interest
to nature conservation (Bibby et al. 1992)
Since the second half of the nineties, base stations for mobile telecommunication have been spreading across the urban centres. These base stations have increased the electromagnetic contamination “electrosmog” in the urban centres. The fundamental reason for that is that these devices produce 900 for analog and 1800 MHz for digital transmission pulsated waves that interfere in the nervous system of living beings. There exist many scientific studies warning about the danger of this kind of electromagnetic radiation (MRW, microwave radiation) for health in human and living beings (see Hyland, 2000). It is forgotten that not only humans, but also animals who are exposed can suffer such impaiments to their health because of field exposure in the vicinity of transmitting antennas (Marks et al. 1995) and show conspicuous behavioural abnormalities (Löscher & Käs, 1998).
Synergic interactions between electromagnetic fields with different frequencies have already been described on a cellular level (Löscher & Liburdy, 1998).
Furthermore, some studies warn about the effects of such radiation on reproduction ; such as, decreases in sperm counts and smaller tube development in rat testes (Dasdag et al., 1999) and increases in embryonic mortality of chickens (Farrel et al., 1997; Youbicier – Simo et al., 1998).
The significant increase of micronuclei in erytrhocyte of cattle grazing near a transmitting is an indication of a genotoxic effect of the exposure (Balode, 1996). Genetic effects on hamster and rats of microwaves have been reported in various studies (Garaj-Vrhovac et al., 1991, Lai and Singh, 1995, 1996 y 1997)
The high frequency RF fields produced a response in many types of neurones in the avian Central Nervous System (Beason & Semm, 2002). Microwave irradiation affects central cholinergic activity in the rat (Lai et al., 1987). Also the activity and learning memory tasks of the rat (Thuroczy et al., 2001). That electromagnetic fields (EMFs) emitted by mobile phones have effects on blood-brain barrier permeability
(Shivers et al., 1987; Fritze et al. 1997, Töre et al., 2001) and damage some neurones in the brains of the rats (Salford et al., 2003). In view of the previously known effects of electromagnetic fields it may be
possible that the observed abnormalities are related to the microwaves exposure.
“The need for further study are no excuse for inaction. The crucial point is that these figures constitute a strong signal that we can not ignore”.
1) POPULATION MONITORING OF HOUSE SPARROWS IN VALLADOLID (SPAIN).*
? Alfonso Balmori Martínez.
*This study was carried out to be published in a scientific review. A summary
containing the methodology used and the main results achieved is showed bellow.
a) Bird Census at point counts of the city.
32 point counts placed in small squares and tree-lined streets of the city were chosen. At each point, a census of the number of sparrows was carried out and the electromagnetic contamination (Microwave radiation) levels were measured once per month between October 2002 and February 2003.
Results and conclusions
During this study the sparrows at several points and streets of the city containing high electromagnetic contamination disappeared.
Although, finding sparrows at these points is rare, they occasionally go back looking for some food and settle again when the contamination levels decrease. They gradually leave all the contaminated areas; it doesn’t happen quickly. At the same time, the number of sparrows tends to increase in low contaminated areas. Therefore, there is a flow of sparrows moving from high to low contaminated areas.
EVOLUTION OF THE NUMBER OF SPARROWS AND THE ELECTROMAGNETIC LEVELS IN HIGH CONTAMINATED (EMF) AREAS
LEVELS OF EMF
The levels (mean) in high contaminated areas (EMF) (n= 12) increased from October to December, decreasing subsequently until February; while the number of sparrows (sum) progress in the other way (see chart).
A very strong negative correlation R= -0.90 (p<0.05) between the mean electromagnetic field levels and the number of sparrows existing in contaminated areas was achieved.
On the contrary, a correlation in low contaminated areas (n= 12 points) wasn’t found.
EVOLUTION OF THE NUMBER OF SPARROWS AND THE ELECTROMAGNETIC LEVELS IN LOW CONTAMINATED (EMF) AREAS
LEVELS OF EMF
These results show that the number of sparrows increases or decreases depending on the electromagnetic contamination levels (EMF) at these points.
Sparrows are specially abundant in small squares or places well protected by the screen effect caused by buildings. They are also found in high contaminated areas but taking refuge in small safe redoubts.
They avoid establishing in the antenna’s main lobe direction (beam); however, they are sometimes found under it, taking advantage of the
umbrella effect. Finding sparrows protecting themselves from EMFs in places where the waves don’t reach, despite of being near base stations, is not rare because of the screen effect caused by buildings. Furthermore, it was observed that some areas where those base stations were took down were reused by sparrows and vice versa.
b) Line transects.
Two different routes approximately 2 Km long each were planned for the outskirts and
the city centre and covered every day. The number of sparrows at each stretch was
registered by noting the points where they were found between October 2002 and
Provisional results and conclusions.
A gradual disappearance of sparrows in the most contaminated (EMF) streets and
squares was observed. The number of sparrows decreased in the city centre, increasing
in the outskirts (See the chart).
October November December January February
NUMBER OF SPARROWS (Mean)
They are usually found on the ground or in low bushes and in places safe from the
waves by walls or buildings causing screen effect.
Some specimens presented partial albinism in their feathers or couldn’t fly properly.
Importance of these results related to the decrease of sparrows in the United Kingdom.
The results of the monitoring carried out in Valladolid provide us some possible causes
to explain the decrease of sparrows in England.
Electromagnetic radiation could produce the following effects:
- Effects on reproduction.
- Effects on the circulatory and central nervous system.
- Effects on the birds health and well-being (microwave syndrome).
- Indirect effects due to food shortage caused by electromagnetic contamination (death of insects).
2) POPULATION MONITORING IN WINTER SLEEPING PLACES.
? Alfonso Balmori Martínez
A) Starling’s sleeping places (Sturnus vulgaris)
Daily observation and tracking.
Results and conclusions
Displacement and division of the main sleeping place into smaller ones. Occupation of low contaminated points of the city to stay the night.
There was always a rather small group of recurrent specimens that didn’t even leave.
It was unknown if they were the same specimens or if there was a changing.
B) White Wagtail’s sleeping places (Motacilla alba)
Monitoring a winter sleeping place in a Lygustrum japonicum under a lamppost near a small antenna emitting high microwaves radiation levels.
Results and conclusions
A gradual removal from the source of contamination was observed. Traditionally (prior placing the antenna) the most occupied tree was few metres from the antenna. The specimens moved to far away trees or even to near points, where sleeping places didn’t exist before.
There was a slow process of desertion of the sleeping place and there was
always a rather small group of recurrent specimens that didn’t even leave. It was unknown if they were the same specimens or if there was a changing.
3) OTHER COMMENTS ON WILDLIFE AND ELECTROMAGNETIC FIELDS.
? Alfonso Balmori Martínez
Kestrel (Falco tinnunculus)
A general disappearance of the kestrels breeding every year in roofs placed near base
stations for mobile telecommunication was stated.
White Stork (Ciconia ciconia)
Although this specie is quite opposed to abandon the nest, even in adverse conditions, the nests placed near the phone mast´s radiation beam gradually disappeared. A decrease of young birds and increase of death rate was observed in nests placed near base stations for mobile telecommunication. The safest pinnacles from radiation were used to alight, gradually leaving those highly exposed to the waves.
Rock Dove (domestic) (Columba livia)
Many dead specimens appeared near phone masts areas. They took refuge and formed groups in places safe from radiation. Many carrier pigeons were lost supposed by the existence of electromagnetic fields affecting their sense of direction (see Bardasano & Elorrieta, 2000).
Magpie (Pica pica)
Anomalies were detected in a great number of specimens at high contaminated points (MWR); such as, plumage deterioration, especially in head and neck, locomotive problems (limps and difficulties to fly), partial albinism and melanism, especially in flanks, and a tendency to stay long in low parts of the trees and on the ground.
Collared Dove (Streptopelia decaocto)
Despite of being an expanding specie, the number of specimens decreased in the whole city. At some points, where they were abundant, they disappeared when Phone masts were settled. Some specimens were found taking refuge in places safe from the electromagnetic waves.

Are you able to contact Dr Martinez?
I believe he also did some research on the disappearance of insects?
There is a £5000 prize offered by The Independent newspaper as to the disappearance of sparrows from the UK. It has to be published in a scientific journal.
There was a paper on the fact that sparrows second hatches are not surviving due to a lack of insects. The Independent said it was getting close.
Perhaps Dr Martinez would like to send in his work?

Here is his E-mail address.
I am copying your quote and sending to him, and then we will have to see what happens.
You could write to him as well.

I received interesting & important posts in response to the Canary story (that was sent by Frans van Velden from the Neatherland),
It is interesting to note that in Osafia, the Druz village that removed antennas because of more than 200 cancer cases (15 new cancer cases were diagnosed only last month), birds disappeared from the village when the antennas were there, and now with no antennas- birds are back !!
Here are the posts - concentrated together they give quite a strong picture

The National Research Council of Canada did lots of studies on the non-thermal effects of microwave radiation on birds in the 1960s, before the wireless industry took control of the science. They found that bird feathers acted as dielectric receptors. Birds that had been plucked under anesthesia showed no reaction to radiation until the 12th day, when their feathers started to grow back.
Studies also showed altered EEG patterns, escape behaviour, other signs of stress in the form of vocalization, defecation and initiation of flight. Parakeets chose an unradiated feeder over a radiated one. Domestic fowl [Leghorns] increased egg production by 13.7% under radiation. Unfortunately, the mortality rate of the radiated colony was double that of the control colony. Their exposures ranged from 0.2 uW/cm2 to 360 uW/cm2. Young chicks exposed to 25mW/cm2 collapsed on the floor of the cage and remained in that position until the radiation was turned off. Time to collapse ranged from 5 to 20 seconds.
Mike Repacholi at one time was with Health Canada and certainly would have had access to these studies. I wonder if WHO recommendations will include this science?

From Larry Blackhall, Canada, who is studying the subject, this is part of his research :
National Research Centre of Canada - (NRC)
Scientific peer reviewed and archived laboratory controlled studies done by the NRC of Canada demonstrate conclusively the harmful effects of electromagnetic radiation on living systems. These studies are available through the NRC archives.
To obtain copies by telephone call 1 800 668 1222 or visit their website at http://www.nrc.ca/cisti .
There is a nominal charge of aproximately $12 cdn.
Here are three brief relevant extracts from three of the studies;
1. Extract from LTR-CS-113 by Dr J Bigu, 1973, titled:
"Interaction of electromagnetic fields and living systems with special reference to birds."
During the initial stabilizing period the egg production of each colony was the same, but following the onset of radiation the egg production of the radiated colony increased to a higher level at which it remained essentially constant. In terms of the total number of eggs produced the diference amounts to an increase of 13.7% - an increase that could be of economic significance in raising poultry provided other, and undesired, interaction effects do not appear.
However the mortality rate of the radiated colony was almost double that of the control colony through each of phases A and B.
2. Extract from LTR-CS-18 by Dr J A Tanner, 1969, titled:
"Effects of microwave radiation on Parakeets in Flight"
Conclusion: The results obtained in this experiment indicates that microwave radiation has an aversive effect on birds in flight comparable to that previously observed in caged birds. This leads the way to a possible solution of the bird hazard problem in aviation.
3. Extract from LTR-CS-89 by Dr. J A Tanner, 1973, co-authored by Dr. Romero-Sierra, Dept of Anatomy, Queens' University, Kingston, Ont., titled;
"Bird Feathers as Dialectic Receptors of Microwave Radiation."
Depending on many factors the use of microwave radiation can be detrimental or beneficial to humans. One beneficial use of microwave radiation is to reduce the hazards of birds to aircraft. This forms part of an extensive program designed to shed some light on the complex nature of the interaction of microwave radiation with biological systems.

More mobiles, and sparrows take flight
# Posted: 31 May 2006 04:20
New Delhi, Nov. 30
THE wireless telecom revolution is catching on at the expense of a tiny winged creature — the house sparrow. The tiny birds are fast disappearing from cities "contaminated" with electromagnetic waves arising out of increased number of mobile handsets.
According to Dr S. Vijayan, Director of the Salim Ali Centre for Ornithology and Natural History (SACON), "A number of studies has been conducted to find out the relationship between the increase in electromagnetic waves and the decrease in the number of sparrows. A positive correlation has been found between them."
"There have been studies in Spain which showed that sparrows disappear from cities where electromagnetic contamination is very heavy," Dr Vijayan added.
A study was initiated earlier this year in London by the British Trust for Ornithology to investigate whether the explosion of electromagnetic waves from portable handsets is wiping out sparrows in London. The British study involves 30,000 birdwatchers who will examine the urban sparrow population near cell-phone masts, where electromagnetic fields are most concentrated.
London has witnessed a steep fall in its sparrow population — a 75 per cent fall since 1994, which coincides with the emergence of the cell-phone.
Electromagnetic waves travel through the air to the cell-phone masts located above tall buildings in the cities. These waves then travel to and fro between the handset and the tower while one is using the handset, and this results in increased electromagnetic contamination in the air.
The rapidly increasing number of cell-phone subscribers is resulting in higher concentration level of electromagnetic waves in the air which clashes with the earth's electromagnetic field.
Dr Vijayan also pointed out that sparrows are found to be disappearing from areas where mobile towers are installed.
SACON has also initiated a detailed study to find out how exactly these small birds are being affected.
"These are all circumstantial evidences. Now we need to prove how it is exactly affecting the sparrows. My feeling is that it probably affects their central nervous system. We are conducting studies with inputs from various cities on the falling number of sparrows in which the effect of electromagnetic contamination from mobile phones are also being examined," Dr Vijayan said.
He said increased exposure to electromagnetic waves also affects small animals. For example, in rats, it is found that the sperm count has decreased while in the case of chicken embryonic, mortality has become very high. There could be more examples, he added.

Subject: Fw: Re caged birds -canaries etc
A farmer who was breeding ostriches about a kilometre from the radio tower found some of the chickens did not develop feathers.
Subject: EMF in the barnyard (fwd)
Dear Wolfgang Scherer
We were very interested in your account of radiofrequeny radiation (RFR)effects on cattle and birds on the Bavarian farm. Of particular interest were the effects on the birds, as we have documented three cases of RFR effects on birds here in Sydney, Australia.
We thought you may find this of interest also. The exquisite sensitivity of the canary, and it would seem other birds, is obviously incompatible with the radiofrequency radiation (RFR) associated with cellular phone transmitters. A warning for the human population?
We wonder if it would be a useful exercise to survey the caged bird population within a given distance from mobile phone base stations.
Following are the cases we have documented.
Case 1.. Fairlight NSW : Unusual behaviour of flock of approx. 17 black crows that usually roosted on the roof of a high rise apartment block.
After the installation of a mobile phone base station (MBS) nearby resident noticed the birds became noisier and unsettled. This behaviour continued for about two weeks-the birds are now no longer in this neighbourhood.
Case2.. Caringbah NSW : Within 200 metres of a MBS Bantam hens and roosters died unexpectedly from unknown causes, within a short time of the installation of the MBS.
Note: On the same premises, a family of two adults and three young adults each progressively developed 'microwave hearing' and moderate to severe headaches after the same MBS installation.
The headaches diminished after alterations were made to the electricity power supply in the street. (Details available on request)
The microwave hearing associated with the MBS continues.
Case 3...Kirrawee NSW: For a number of years an exotic bird breeder had approx. 350 birds located one hundred metres distance from a radiofrequency antenna used by a paging service. Within four months of the installation being upgraded to a mobile base station (MBS) most birds refused to breed, those that did breed prematurely removed the young from the nests. Two only young birds survived the season, one only has feathers, the other none at all.
Some species became aggressive, defeathering their mates.
The owner has since moved house.
