Your notes and queries for Ethna Viney
We have found the regurgitated stuff mentioned in Eye on Nature on July 1st. It can range in colour from pink to light purple. We dissected it and found a mixture of pulp and seeds regurgitated by our jackdaws and rooks. The seeds germinated and produced little ivy plants. Ulli Peiler Ballymote, Co Sligo
■ The pulp of ivy seeds is purple.
For the first time buzzards have nested in the top of an ash tree in a woodland in Co Meath. This photograph taken by a neighbour shows the chick almost fully fledged. Clive R Symons Macetown, Co Meath
I saw the plant in my photograph on a stone wall inside the monastic cashel on Inishmurray, off Co Sligo. Eamon McPartland Grange, Co Sligo
■ The plant is navelwort, which grows on old walls, on cliffs and in rocky places.
Can you identify the insect that I found on a lily plant? John Derby Cashel, Co Tipperary ■ It is the red lily leaf beetle, from looking at your photograph. My grandson found the whelk shell in the photograph I’m sending you at Laytown beach, Co Meath. It is about 12cm long and 1-1.5mm thick. How big can these animals be?
Eyes on nature: one of the buzzards that Clive Symons’s ■ neighbour photographed in Co Meath; Vincent Devlin’s photograph of regurgitated pink stuff that Ulli Peiler has responded to this week; and navelwort on Inishmurray Fred Fitzsimons Carrickmacross, Co Monaghan
■ Common whelk shells can normally reach 11cm, so yours is particularly large. Whelks grow their shells around a central axis, adding new material from the mantle at the aperture. Scientists have found that the shell thickens most when the whelks are subject to predator pressure from crabs, lobsters and starfish.
