Wildlife 
Researcher Judy Hoy has been documenting 
diseases & birth defects in wildlife for 50 years. 
Since 1995 she has seen increases in: 
Underbite and malformed jaw 
Enlarged right heart ventricle 
Spots and bleeding of lungs 
Weak calf syndrome 
Hoof problems 
Tumors 
Malformed thymus gland
 Prior to 1995, I saw only one animal with 
tumors that looked like cancer. 
 After 1995, I have seen many birds and 
mammals with cancer. 
 This photo document gives examples of tumors 
and cancers I have observed on animals since 
1995. 
 Several more goats and quite a few pigeons 
with tumors I have observed are not in the 
document. 
 One goat had tumors all over her udder.
 In the first 25 years of rehabilitating birds, I 
never saw a single bird with tumors such as 
those shown in the following photos. 
 This is just a sample of what has been 
observed and reported, with regard to tumors 
on mammals and birds between 2007 and 
2010, when huge new amounts of Roundup 
began being used on Roundup Ready Alfalfa in 
our area and in states upwind.

Pine Siskin with cloacal tumors from Thompson Falls, MT, August

Female Pine Siskin with a tumor on the neck. Taken at Thompson 
Falls, 
Montana by Jim Greaves on April 28, 2009.
Tumors on the breast muscle and internal organs of an immature 
male Red Crossbill from Ravalli County, MT, in spring 2009.
Male House Finch with a large tumor on its neck.
Tumors on the intestines of a female Red-tailed Hawk. Bird died 
August 
2, 2008.
American Kestrel heart with large tumors. This kestrel died in 
late 
summer of 2007.
Adult male goat which had the liver tumors 
shown above. The goat died on June 5, 2008.
This older female sheep was euthanized in February 1010, because of 
the large tumor on the front of the mandible.
Skin tumors on a male white-tailed deer in Ravalli County, Montana. 
There are at least three tumors on the face, one on the left side and at 
least two on the right side. There are at least two tumors visible on the 
body, one on the left shoulder and one on the back. Also, as is evident 
in the photo, this deer has an obvious severely underdeveloped lower 
jaw commonly called mandibular brachygnathia.
This tumor came from the intestinal area of a 6-year-old 
captive female wolf, verified by testing as cancer. This tumor was 
approximately 18 cm across.
