question about fishing under the birds

[saltysully]

I have a 20 foot sea hunt and have tried to catch the specs under the birds. However, each time i approach the birds and no matter how slow or fast I approach them, they take to the sky. I think it may be because either the boat is bright white or the center console is kind of high, or the whole boat itself sits pretty high off the water. any of you guys have any tips or suggestions?
