Inflammations in the oral cavity, &nbsp;throat, crop and oesophagus make drinking and eating difficult and often food cannot be swallowed properly or is regurgitated and falls out of the beak. The birds die of starvation or suffocation, sometimes swiftly. Similar symptoms are also found in cases of avian pox, and as such, examination is required to uncover what disease the bird suffered from.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Preventing transmission<\/h3>\n\n\n\n<p>When feeding birds in your garden, it is important to take certain hygienic measures to prevent the transmission of diseases between birds in a feeding place.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Clean feeding tables daily and disinfect frequently. To disinfect a feeding tabel, a diluted bleach-solution (5% sodium-hypochloride) can be used. Other commercial disinfectants can also be used.<\/li><li>Rinse feeding tables thoroughly and let them dry before reusing. Move feeding tables regularly to prevent infectious agents from accumulating underneath.<\/li><li>Clean bird baths every day, and let them dry before refilling with water.<\/li><li>During an outbreak feeding should be reduced; stopping feeding for two to four weeks is optimal.<\/li><li>When cleaning, wear rubber gloves en wash hands thoroughly afterwards, especially before drinking or eating. Use disposable gloves when removing dead birds.<\/li><\/ul>\n\n\n\n<p>For older articles of the DWHC and more information on \u201cPigeon canker\u201d, go to: <a href=\"https:\/\/dwhc-dev.wp.hum.uu.nl\/en\/ziekten\/trichomonas\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/dwhc-dev.wp.hum.uu.nl\/en\/ziekten\/trichomonas\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This winter, the DWHC has received more reports on dead pigeons.
