Be sure to check for sharp edges and doors that are not easily opened, to prevent accidental escapes. The addition of several toys will not only help keep these active guys busy but help keep beaks in good condition. Lovebird's beaks are made of keratin which grows continuously, just like human finger nails. Chewing and destroying wood toys and perches helps to keep beaks trim. Natural perches of varying thicknesses placed at different levels in the cage will allow greater climbing mobility and gives them a choice to select the most comfortable spot to roost.
Love birds are excellent flyers.
Keep flight feathers trimmed to prevent accidents and accidental escapes. Nails will need to be trimmed about every 6 to 8 weeks. An annual well bird check is a must for all parrots including Lovebirds. Weigh your bird regularly and record weights so that you will be aware of any weight loss. Watch for signs of illness such as labored breathing, excessive sneezing, sitting puffy, panting, discharge from nares, weight loss, behavior changes, lack of appetite, lethargic, etc.
