    Avian life in Tunisia has experienced a dramatic event in recent days,

    following the mass mortality of thousands of birds (preliminary estimate of 10 000 birds) under mysterious circumstances. The circumstances are, at present, unexplained.

    Several sources confirm a significant increase in mortality of wild birds in the wetlands of the north (Lake and Sabkhat Sejoumi Echkeul and Ghar el melh). Similar cases have been reported from Ontario in Canada, Falkoping in southwestern Sweden, Louisiana and Arkansas (USA), and now Tunisia.

    Veterinarians are trying to find an explanation for this unusual incident that has appeared for the 1st time, at this size, in Tunisia:

    Hypothesis 1: The System PBX (telephone network) is singled out because it generates magnetic fields that affect the nervous system of birds.

    Hypothesis 2: Walking difficulties have been described among the symptoms. It seems that preliminary investigations are moving towards a conclusion of botulism. Botulism affects the nervous system, is often foodborne, and is caused by the action of bacterial neurotoxins (botulinum toxin) produced by _Clostridium botulinum_.

    Hypothesis 3: These deaths are collective mortalities following the destruction of the ecological niche of some species by the action of pollution or urban development, which make the possibility of populating this environment close to zero or low.

    Everything possible must be done by research organizations and Tunisian environmental investigation forces to decipher the mysterious event that threatens the birds of Tunisia.

    "Observation of this phenomenon in Tunisia has now gone on for about 2 weeks [23 Oct - 11 Nov 2011]. The deaths of 500 birds have been reported in Ichkeul in Sebkhet Sejoumi in the region of Bizerte and Hammamet.

    Several teams from the association "Les Amis des Oiseaux" and other birders have traveled to many wetlands (and other sites) in the north and south of Tunisia, and after heavy rains, we have found more unusual mortality.

    We have no confirmed explanation for the thousands of birds that have been found dead under unusual circumstances during the past 2 weeks, but we expect an official communication from the authorities, especially with regard to the results of sampling done on dead birds and analyses of wetlands involved."

    [The episode apparently is taking place in wetlands, but there is no mention of the species affected, ages, or other important details of the outbreak. Given the acute characteristic of this die-off, it could be botulism or another toxin or contaminant, or an infectious disease.

    More information on the die-off and on the current investigation is hereby requested - Mod.PMB]

      Translation (Google)

      Bird mortality is caused by botulinum toxin (Declaration)
      16-11-2011 12:49:07

      These days a high mortality of wild birds was recorded in the wetlands of northern namely Lake Echkil and Sabkhat Sedjoumi.

      Following these cases, the general administration of veterinary interest in collaboration with the Forestry Administration, the Institute of Veterinary Research and the Pasteur Institute have made ​​a few samples.

      The first tests have ruled out avian influenza and preliminary examinations are moving towards a anadémie of botulism caused by botulinum toxin, which causes an ascending paralysis. This toxin is safe for humans but it would be better not to touch dead birds or to take precautions such as wearing gloves....
