The long thin seedpods resemble horns, hence the name.
The waxy leaves have a hairy surface which enables the plant to retain moisture.
The wind was pretty strong so we were surprised to spot this female Grayling, as it lanaded on the shingle, a first for me, it settled into a hollow, its forewing tucked tightly into its hindwing as it sheltered from the wind.
Then a smaller butterfly stopped by, a female Common Blue sheltered down to bask amongst the shingle.
It wasn't just the butterflies that were making the most of the weather.
From the nearby hide, at a distance we saw 10 Spoonbill, Ruff, Green Sandpiper, Shelduck, Lapwing, Teal, Ringed Plover.
On the raised path between the marshy pools the flanking vegetation provided shelter for plenty of Common Blues, Gatekeepers and 10 or so Common Darters.
The moment we turned back we were confronted by a hobby or sparrowhawk flying along the channel next to us and in an instant it dove down into the reeds, according to the listings both birds are regularly spotted on the reserve.
After a pitstop return to the visitors centre we crossed the road to visit more hides. On crossing a bridge we heard a plop in the water below and spotted a Water Vole unconcerned by the attention and remained for approximately 5 minutes until the bridge was full of people before it decided to disappear.
A few metres away I got my first female Wall Brown together with the first Painted Lady of the year.
A few metres further a male Migrant Hawker at rest on vegetation.
To top it all off we popped into Cookies Crab Shop in Salthouse for a crab and crayfish salad, where two Marsh Harriers were spotted on the way.
As we were heading to Sheringham for an ice cream we spotted a number of birders with scopes heading down a lane, needless to say the ice cream took priority but on our return Andrea popped down to check out the fuss and caught a distant glimpse of a Lesser Grey Shrike, the talk of Norfolk birder for the rest of the week. Phew!
