708  Hand-Rearing Birds

              Common Medical Problems and Solutions

            Caught by Cat
            Victims of cat (or dog) attack often have punctures, lacerations, fractures, internal bleeding from
            crushing bites, and respiratory issues, including ruptured air sacs. Antibiotics must be given for
            7–10 days depending on the severity of the injuries. Amoxicillin, cephalexin, enrofloxacin, and
            ciprofloxacin are the preferable drugs. Avoid trimethoprim sulfamethoxazone since some species
            are sensitive to it. For birds with severe injuries, wound treatment is needed (this is covered in
            Chapter 1). Ruptured air sacs should be left to resolve on their own unless they are causing the bird
            great discomfort and/or an inability to maintain balance or eat.


              Metabolic Bone Disease
            Well‐meaning rescuers create more complications by feeding birds inappropriate foods. Robins
            and mockingbirds are very susceptible to metabolic bone disease (MBD), which is typically caused
            by a diet deficient in calcium. Older nestlings or fledglings that demonstrate difficulty in standing
            or have drooping wings may have weak or broken bones. Supplementation with oral calcium glubi-
            onate or calcium carbonate (150 mg/kg SID or BID), a balanced diet, light supportive splints, and
            padded surfaces may help. If the disease is advanced (i.e. there are joint or limb abnormalities),
            euthanasia should be considered. See Duerr et al. (2017) for information regarding management of
            orthopedic injuries in small birds.


            Pesticides

            Birds that feed on lawns and cultivated berries may be inadvertently passing on pesticides to their
            young. If this issue is suspected, the only treatment available is activated charcoal.


            Viruses
            Avian pox and West Nile virus (WNV) may be more problematic in some areas or regions as out-
            breaks occur. Pox is a very contagious disease, transmitted through insect bites or direct contact,
            whereas WNV is transmitted by mosquito vector. Pox treatment can be labor intensive, and the risk
            of infecting other birds in care must be considered.


            Parasites
            Some  thrushes  and  thrush  relatives  present  with  infections  from  more  than  one  parasite.
            Typical  parasites  for  American  Robins  are  coccidia,  gapeworm,  capillaria,  and  occasionally
            tapeworm and roundworm. The protozoan  Trichomonas gallinae may occur in these species
            and may be diagnosed by a throat swab. Starlings carry many of these infections and may also
            present  with  giardiasis,  caused  by  an  intestinal  protozoan.  Routine  fecal  exams  are  recom-
            mended,  especially  for  nestlings  that  have  (smelly)  diarrhea  and  are  underweight  for  their
            developmental age. Many rehabilitation centers have protocols in place for prophylactic treat -
            ment. Remember, one fecal sample is just a point in time in a parasite’s lifecycle, so even if an
            initial sample is negative, results can change over time in the captive setting. Prophylactic med-
            ications such as ponazuril (3 days) and ivermectin (one dose) may be given to fledglings and
