More like a carrion crow, but at just under five Euros that's okay!
I have 3 set (2 and 1 as Päärchen on the other side balcony) because crows are nunmal colony birds.
The 3 to the 2 pigeons indicate: "Here is busy"
On the first afternoon, the 2 pigeons cancel several landings and are not seen after a short time ... a penis army feels sichbar uncomfortable. :-)
Meisen take no notice of the dummies, but this is certainly desired.
Day 2 - No pigeons spotted, no traces ... Meisen still active ... cat wants to mock attack (LAUGHING)
Day 3 - A pigeon check it out, but disappears with sichbarem discomfort again ... by reacting a crow is quiet again.
Day 4 - Day 3 as ... the cats have slowly become accustomed. - A woodpecker can not interfere.
Day 5 - Fresh morgentlicher pigeon droppings suggests the presence ...
A few days later ... at least a dove can be moderate rain down on the balcony.
Conclusion:
At least the dummies do not seem the presence of pigeons (initially) limit somewhat ... more (unfortunately).
Who likes crows, they can still use it as a fun decoration.
