Any tips to stop focus on birds?

My 8 month old pup is going great with training. We are doing Susan Garrett’s recallers and so much progress!!

One specific thing that has been a problem is birds. She started chasing them once or twice and based on suggestions we completely stopped going to the park during peak bird times. This is to stop her from rehearsing.

The thing is - she still goes into zombie mode when she can see the clear sky in an area where she can find a bird. She can’t hear me in this state. I physically Up her and get to a place with less distractions and snap her out of the zombie state.

Any experience with your dogs? Any suggestions on what I should be doing?

Thank you so much. I love my pup so so much. The other day she was in the zombie state and was jumping up and got her paw in between the fence and I was so shaken after that. Thankfully no harm was done but I am really really worried.
