Mystery plant/flower?

[mkat]

This one should be an easy one for you. It's ubiquitous in our area but we don't know what it is.
Any help is appreciated

Looks like basic Coreopsis to me. There are a number of variations, but this one looks like the basic good old standard.

Those thin leaves and bright yellow flowers leads me to think:

Threadleaf Coreopsis

Thanks ya'll! I knew you guys would have the answer.
I was intrigued by the name "Zagreb" as well.
Apparently they are colloquially called "tickseeds" as well but I don't like that name :s so coreopsis it is!
