Psychologically, you may feel safer by tuning the Wx radar. But I beleive it is a midwife tale.
Have a look at Venice airport, Italy Jepp 10-9. They instruct the pilots to switch on the Wx radar for take off and landing due to birds in the vicinity. I dont know who gave them this false idea.
Birds have the 5 senses possed by humans (I seem to recall reading somewhere that they hear at same freq as humans)
But who knows for sure other than the birds themselves ?
