USA are essentially urbanized (South and Pruett- 
Jones 2000.1 in contrast to their native range where 
the species is mostly rural. The Monk Parakeet's 
ahihty to thrive in human-altered environments 
often creates conflicts and the need for aggressive 
management (Neidermyer and Hickey 1977. 
Avery et al. 2008). Flexible nest-building behav- 
'er. which contributes to the Monk Parakeet's 
success, is exactly what has created conflict. The 
•species is a valued, charismatic component of 
'ocal avifauna in many communities, but the 
propensity of these birds to select man-made 
-Luctures as nesting substrates is increasingly at 
odds with safe, efficient operation of electric 
u 'ilitv facilities (Newman et al. 2008). It would 
nnI be surprising if additional conflicts arise as 
Monk Parakeets colonize new environments (Sol 
e 'nl, 1997), given their dietary flexibility (South 
j nd Pruett-Jones 2000 ) and dispersal ability 
(Gonsalves da Silva et al. 2010).
