predation of threatened bird species in Florida by the "butcher" bird

edit

I've heard that certain threatened bird species are affected by the clearing of trails in wooded areas of Florida. It has been claimed that these trails make nests vulnerable to predation by the "butcher" bird. Is the "butcher bird the Loggerhead Shrike or a non-native species?

I believe the butcherbird is a synonym for the Loggerhead shrike: Craig R. 1978. An analysis of the predatory behavior of the Loggerhead Shrike.

Can anyone point me to additional information?

Consistency of conservation status

Just out of curiosity, if the species is of least concern according to the IUCN, how is it that within the body of the article it is described as "critically endangered" in Canada? 75.27.166.91 (talk) 21:37, 10 October 2010 (UTC)Reply

The IUCN assessment is for its global status. Its main range is the US and Mexico, where it has a large population, so overall it's not threatened. that doesn't mean that it can't be at risk in parts of its range, like Canada. Individual subspecies can also be at risk. The Wolf as a species is of least concern, but the subspecies Canis lupus baileyi, the Mexican Wolf is extinct in the wild Jimfbleak - talk to me? 06:04, 11 October 2010 (UTC)Reply

Dimensions

I see nothing re the size of these birds. — Preceding unsigned comment added by 98.82.124.202 (talk) 17:27, 2 January 2013 (UTC)Reply
