That's quite a leap from "first documented" to "if nest usurpation behavior becomes prevalent".

_D. Niler Pyeatt_ 
(http://www.wbu.edu/academics/schools/social_sciences/pyeatt/bio.html)  first noticed American Robins nesting  in a cottonwood tree 
outside his office window at Wayland Baptist University, in  Plainview, 
Texas, north of Lubbock, in April 2014. Days later, he saw a Eurasian  
Collared-Dove taking interest in, approaching, and eventually sitting in the  nest 
when the robins were absent. 
Within  two days, the collared-dove began chasing the attending robin off 
the nest. “The  collared-dove would land on a branch next to the nest with 
the robin and puff  its chest and flap its wings rapidly until the robin left 
the nest,” Pyeatt and  biologist _Andrew Kasner_ 
(http://www.wbu.edu/academics/schools/math_and_science/kasner/default.htm)  report in the _Wilson  
Journal of Ornithology_ (http://www.wilsonsociety.org/pubs/index.html) . 
Just  a day later, the collared-dove drove the robins away and took over 
the nest. In  late May, the collared-dove fledged two young from the nest. 
It  was the first documented piracy of a songbird nest by a Eurasian 
Collared-Dove.  The species is invasive and widespread in North America, ranging 
from central  Alaska to western Panama and the Caribbean. 
“The  potential exists for significant effects on songbird nest success 
throughout the  range occupied by collared-doves if nest usurpation behavior 
becomes prevalent,”  the researchers write. “Such effects would not be 
restricted to urban areas, as  collared-doves are rapidly expanding into rural 
areas as they disperse along  human-altered landscape features.”
