Nesting ducks

Hello.

I live in an apartment block in Croydon. The block is rectangular in shape and fully surrounds a communal podium area.

In the podium area, there are a number of planters about 2m square. 

The management team have informed us that there are some ducks nesting in oe of the planters-although they didn't say what type. The Planter has been taped off and local wildlife protection have been informed. the management team have advised us that they will be monitoring the situation and have advised us that if any resident spots any ducklings then they are to email the development manager, who will notify the wildlife protection team who will come and remove the ducks and ducklings.

The management team have circulated an email to all residents advising them of the situation.

I've been up to a higher floor to try and spot the nest, but I cant see anything. there are a few plants in the planter, and a small tree in the middle, but I cant spot the nest.

Any advice on what I can do?

I'll try and keep an eye on them.

Cheers.

Rich.
