We present the results of the biometrical
analysis made on a sample of 17 juvenile rooks,
Corvus frugilegus (L.), captured in the city of
Iaşi, during the emancipation period, between 11
th
of May 2010 and 5
th
of June 2010.
Thirteen of these birds came from a nesting
area situated in the northern part of the city, along
the Boulevard Carol 1
st
, between the buildings of
Romanian Academy, Iaşi Branch and the Super
Copou Store, where old trees are predominant.
The rest of four individuals were captured
from two poplar plantations, located in southeastern part of the city.
Willing to gather metrical and weight
related data, we captured 16 European jackdaw
chicks, Corvus monedula (L.) from Tătăraşi, the
neighborhood situated in the eastern part of the
city of Iaşi, between 26
th
of May 2010 and 30
th
of
the same month.
This species usually build their nests inside
the ventilation holes of the apartment houses. We
choose to study Corvus frugilegus and Corvus
monedula species together because the last one
joins the first when looking for food, defending
from predators and night aggregation. |
