[11] It is classified as a semiregular variable with pulsations of multiple periods of 68.0, 94.9 and 101.7 days.

[12] At an angular separation of 102.9 arcseconds is δ2 Apodis, an orange K-type giant with an apparent magnitude of +5.27.

Both stars are bright enough to be seen with the naked eye under good observing conditions, and the separation between the stars is wide enough to allow them to be seen individually by a person with good eyesight.

Hipparcos data report the distance to δ1 Apodis to be approximately 760 light years, while δ2 Apodis is found to be around 610 light years from Earth.

Consequently, δ1 Apodis itself is known as 異雀六 (Yì Què liù, English: the Sixth Star of Exotic Bird.
