3.
Why be a Batesian mimic rather than cryptic (no warning colours) or aposematic (with
repellent defences too)?
4.
Why are prey sometimes (but not always) polymorphic?
5.
Some predators mimic non-threatening, or even inviting species, or objects, to gain access
to prey (Heiling
et al
., 2003). Compare this 'aggressive mimicry' with masquerade,
camouflage and Batesian mimicry in prey.
6.
Some Australian hosts of bronze-cuckoos often reject cuckoo chicks whereas European
hosts of common cuckoos rarely do so. In both cases, the cuckoo chicks eject the host eggs
or host young from the nest, so hosts lose all their reproductive success from a successfully
parasitized nest. What could explain this difference in host rejection? (Read Kilner &
Langmore, 2011).
