Abstract:

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.

Keywords:

emancipation, predators, exhaustion, cries, feeding, flight, feathering.
