Our campaign against poisoning of wildlife has for the past 4 years focused on the special ground case of Bunyala. Bunyala is remotely located and otherwise latent atrocities against wildlife are easily detected here compared to less remote sites in our republic thereby offering an opportunity to illustrate the threat issues (starting with poisoning), flag up these conservation concerns and furnish the public on the status quo and relevant authorities on need to act. The latter and ultimate intended aim has however on the general remained unattended to leaving us with no options but to act in our own capacity however small.
In our vigilance approach to minimize/prevent the indiscriminate poisonings of birds….and most probably humans in Bunyala, my team and I stumbled on bird trapping/snaring of birds particularly raptors during September 2012. The first discovered case of LOST the Long Crested Eagle snared & killed in Bunyala was an awakening call to watch out for all threats to birds for their protection. The perpetrator’s defence was that the bird habitually took on his newly hatched chicks, a genuinely understandable reason but even then, decent, effective screens/shields for baby chickens against raptors are locally available and sold cheaply. My scouts however purport that some raptors are snared for human consumption. The Long Crested Eagle is a locally abundant species at the site and is said not to be spared by some of the bird-eaters. When I rescued LOST, one onlooker stated in local vernacular that ‘this boy has just snatched away one hell of a rooster that would have supplemented Ugali’. From my stand point, this is sufficiently authentic of the raptor-eating allegation.
It has now emerged that there is more than one motive to killing raptors at the rice irrigation scheme. Raptors kill smaller birds for their meal. I reckon one or two well-fleshed queleas/weaver birds per day are sufficient for an accipiter, a large kestrel or a falcon. Larger raptors like the Ayres’s Hawk Eagle in the locality may go for larger doves but then again just a couple of these per day are adequate. Hundreds of thousands of smaller birds come to feed at the rice scheme which at the moment is a combination of habitats ideal for all species. Certain plots are fallow while others are flooded and being readied for planting. A few have the crop ready and is being harvested but in a majority, the rice crop is maturing up. The maturing/mature crop is the main attractant for parasitic seedeaters and raises concern for raptors which local farmers are aware terrify the seed-eating raiders but are crudely and unsustainably harnessing this use of raptors.

As the raptors hunt in the natural setting, they certainly cause panic as they ambush the smaller birds and the emanating frenzy sends the assailed birds scurrying and scattering away from the rice field. However, the shock wave is only effective over a narrow front of just a few acres leaving many thousands hectares unscathed with the parasitic hordes enjoying their cereal meal!
We have observed that most modes of scaring away the likes of queleas, waxbills and weavers from the crop are ineffective. These range from vocal cord ripping yells, hitting or churning of shakers to human-form scarecrows otherwise just secured polythene bags flapping in the wind. The case of suspending hawks in mid-air to mimic a raptor on decent to a kill is said to work wonders and keeps most if not all parasitic bird species from destroying the rice crop. Our latest victim is a Grey Kestrel that a poacher employed his taxidermy skills to preserve the bird’s feathers and body in perfect condition but for the messed up head and neck that the snap-trap struck the subject.

In an attempt to find out if for sure this method works, I picked a random neighboring plot and realized the farmer in the nearby plot actively engaged in chasing away the birds by hitting on some percussion container (plastic container laden with stones) as the raiding locust birds stubbornly gorged on his crop. The farmer in the plot with the suspended preserved kestrel sat down clearly with little or no concern for the parasitic birds I bet from guaranteed security from the poor murdered watchman’s carcass guarding over his farm!

This is not the only incident and my scouts describe at least one other incident of a raptor that I infered to be the African Marsh Harrier, possibly a juvenile from their description (a mostly all-brown raptor with some white speckling on the nape region harrying just above the rice fields, head down-facing,).
In seeking a solution, one is quickly forced to suggest toxic aerial spraying which we know full well falls in the very category of the misdeeds that our campaign seeks to address. This is because aerial spraying would be indiscriminate, affecting other species and also raptors when they go for the easy, dying intoxicated smaller birds with a further translocation of the poison (and resultant poisoning) to areas afar by the intoxicated, but still able to fly birds. I wish to ask yet again anyone/experts to share information of known effective methods of scaring the parasitic birds away which we could possibly introduce in Bunyala and help conserve our raptors.
