Brandon Hodge, 28, was sentenced at Greenock Sheriff Court (today) after he admitted two charges of animal neglect.
He was also made subject of a 12-month supervision order and ordered to carry out 90 hours of unpaid work.
A total of 18 birds were discovered after police officers and inspectors from the Scottish SPCA carried out a search of a property in Kilmacolm, Renfrewshire, in May 2024.
They found most of the cages stacked on top of each other and encrusted with faecal matter and waste. The surrounding area was strewn with rubbish, maggots and insects.
One bird - a Harris Hawk - had to be euthanised due to its poor condition.
Conditions were so bad they reduced one Scottish SPCA vet to tears.
Anne Marie Hicks, Procurator Fiscal for North Strathclyde, said:
“This was a shocking case of animal neglect.
“Brandon Hodge showed no regard for the welfare of these birds, which were kept in appalling conditions.
“The harm they suffered was unimaginable and the public will rightly be appalled.
“Hodge has now been held accountable following this prosecution and we will continue to prosecute crimes where there is a sufficiency of evidence and it is in the public interest to do so.”
The types of birds found in the house included nine varieties of owls, three American kestrels and a red footed falcon.
Scottish SPCA inspectors said the smell inside the property was overpowering and described the conditions as among the worst they had ever witnessed.
The birds contained within the carriers had no food or water and were covered in dirt, food, feathers and faecal matter.
The cages were too small for them to even spread their wings.
A Eurasian Eagle Owl was found to have broken feathers on its right wing while an American kestrel was missing a foot.
Several birds also had anklets attached to them which were dirty and badly contaminated with faeces.
Many of the animals were later successfully rehomed in locations across Scotland, ranging from Edinburgh Zoo to the Scottish Owl Centre in West Lothian.
