She will instinctually come to familiar sounds... it won't confuse her.
I am reposting part of my original post...
after 24 hours of searching, he has not been spotted
Here are some other ideas and contacts. If a person finds your bird, they may contact one of these organizations or see your poster or advertisement.
· Call animal control.
· Call local veterinarians.
· Call local zoos.
· Call local pet shops. Speak with the managers and let them know. Sometimes people find birds and try to sell them for quick cash. Alert them to possible calls similar to “What does a bird eat that looks like this?”
· Call local police.
· Put LOST PARROT posters along the main roads in and out of the area the bird was last seen, especially near intersections where people are driving slow or are stopping, in the local supermarkets, post office, and even let the fire department know.
· Place a LOST ad in your area craigslist and newspaper(s). If you offer a reward, it may increase the chances of your bird’s return. Post signs in local veterinarians’ offices, pet stores, and apartment bulletin boards (usually near the mailboxes areas). Have your kids post signs on the school’s bulletin board. Post signs anywhere you think they’ll be noticed. You may also wish to offer a reward as incentive for people to call.
· Check the classified section of the paper for “found” bird. Answer all ads. People are sometimes unaware of what they have found. A Congo African grey may be mistaken for the mythical red tailed pigeon by a helpful stranger who is unfamiliar with parrots.
· Contact your area animal rescue/shelters and have them put your bird on file. Make sure they have a way to contact you. Call them every few days to make sure you keep it fresh in their minds. Be sure to ask how long they keep a lost animal on file and be sure to call back and relist your bird if you’re still looking for him/her.
· Contact any local breeders and let them know about your lost bird. Again, sometimes people find birds and try to sell them for quick cash.
· Check with local nearby areas that may have people outdoors in the open such as golf courses and leave a flyer with them. Birds have been known to land on a golfer's head.
· Post on Facebook, it is a great tool for spreading the word
· Check Craigslist for FOUND, FREE, OR FOR SALE Birds. Sometimes people find birds and can’t keep them and then try to give them away or sell them.
On all posters/flyers, ads, etc., make sure you mention how your bird is family to you (and your children). Stress how much you care for your bird and it may help to persuade someone who may not initially intend on returning a found bird to contact you.
Tape a flyer on each side of your car’s back windows. Then, as you drive around looking for the bird and handing out flyers, people will see a rolling advertisement. People will notice and stop to ask. It is an especially good idea if you think your bird is still in the area.
Note: Don’t give out the bird’s band number. If your bird accidentally falls into the wrong hands this could lead to removal of the band.
