Where is your nest????

I don't know what kind of birds these are but they built a nest in my neighbors grill.. The grill lid was closed and they got in through the back of the grill. They kept bringing sticks and grass in the grill and my neighbor thought the wind was blowing it in. So she just kept removing it and throwing it away. Well she woke up one morning and bam there is a birds nest in her grill.. They have left it alone and now there are eggs in there. Soon there will be babies (obviously)... Hopefully the babies will learn to fly before the summer is over so that my neighbors can use their grill..
