Baby Male Bird

LOST PawBoost ID: 73457366


Trabuco Canyon, CA 92688

I lost my yellow cockatiel with orange cheeks, he’s friendly but can be shy with strangers. He’s a social bird that responds to his name “Baby”. He’s a good flyer, but only indoors. This time he accidently flew outside. I am very worried about him and hope that he’s safe somewhere. Please contact me if you find him? I miss him very much and hope that he will be OK. He is probably very dehydrated since it’s so hot out now, please msg me at anytime if found. He’s a very important family member and he must be frightened out there. Thank you.

Frequently Asked Questions

I lost my pet. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet to PawBoost in no time flat. We'll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your pet to our lost & found, and make a lost pet flyer – all for free.

Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your pet's microchip is registered and up to date. If you don't know your pet's chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Costa Mesa community, the better your chances of a happy reunion!
