A target for birds? [SEC=UNOFFICIAL]

["Perkins, Harvey" <>]

Not a cocoon, but the foamy protective egg case of a preying mantis. Not likely to be a target for any bird, but may be parasitised by tiny parasitic wasps.

Subject: [canberrabirds] A target for birds?

In the course of a little garden pruning yesterday, I encountered
several structures about the size of a walnut that I assume are cocoons. Prior
to pruning, they were not especially obvious, being located a few inches inside
of the plant perimeter. However, having pruned around them and left them, they
are now quite visible - see picture.

I am wondering (a) what insect might have constructed
these, and (b) if they are likely to be a target for any birds. Is anyone able
to comment? Thanks in anticipation of any insights that anyone is able to
share.

Regards ... Robin Eckermann
