The Common Whitethroats seem to have upped the size of the insects that they are bringing to the nest.
Marbled White Butterfly: this is only the second park record of this species. It was present in the Wetland Pen, area 32 and would sometimes hop over the hedge and into the nearby area. It seldom settled for more than a few seconds.

It probably came from the Butterfly tent that is situated just inside the eastern boundary.

I think the nearest colony to the park is Brent Reservoir unless they have some on the heath.

I am glad that you saw them, it is always nice to see a new species.
