Thrush calls II : alarm and contact calls

The American Robin has a variety of alarm or contact calls, often heard at dusk:

puck (May, NJ)










puck, tzzap, puk-puk-puk (Nov, PA)

tzzap








puk-puk-puk







chip (May, NJ)











Qui-qui-qui, by a single aggressive bird in a foraging flock. This call is often heard at dusk. At the end of the recording the birds suddenly flush with high pitched flight calls (Feb, NJ).











A musical variant of the call (Mar, PA)












Quiet calls by one bird close to another (Mar, PA).













The whistle call is ventriloquial and is heard when an intruder is close to the nest or in the presence of a hawk (May, NJ).












The Veery also has a number of calls. Are they all alarm calls, or do they have different meanings? Interestingly, Veeries also show a lot of variability in their flight calls.

The Eastern Bluebird has a chatter-like call used both as an alarm call and, as in this case, amongst birds in a migrating flock (about a dozen birds, Oct, PA).
Also heard are trill-like interaction calls, at 6-9 and 19-23s.
