An Accidental Bird Bath for all the Cool Birds In Town

We started yesterday to set up a system to pipe the water from our sump pump even further away from the house (contractor only took it to the foundation wall at our request). We plan on burying and sloping the first pipe which goes out about 10', then connecting that to a slitted pipe which will be buried on top of a 12" trench of gravel, to distribute the water over a larger area.

I had a brainfart and only bought one pipe yesterday so we just have it going out from the foundation on top of the ground and ending in a stand of trees and brush and dumping the water off at the surface. I was going to get the second one and complete the project tomorrow.

But in just one day, the water coming out there has apparently become the place to see and be seen for the neighborhood birds, as a little bathing and drinking pool!! There were at least seven types of birds there in just the five minutes I was watching. If they weren't so easily startled, I'd take a pic; I'll wait until I have the time to be really really still for a long while.

Part of me is really tempted to not bother burying this drain pipe or putting in the slitted pipe, and instead just put up some feeders in the area and keep it as a surface pool. I don't think the water could get stagnant enough to be a mosquito breeding ground, because it would drain into the ground too quickly... could it?

Edited to add: Right now there is a HUGE robin with very vivid coloring (extra-long bright yellow beak and very vivid red breast, both of which I'm sure makes him very popular with the ladies) who has claimed the mini-pond as HIS, and is very aggressively chasing the other birds away if they try to come close. I guess spring has his testosterone pumped up a little high and turned him into a bird version of a macho jerk!!
