NOTE: I am color blind so I'm taking a huge guess here from what I believe I see in your pic.
What is the red and white bird in Hawaii?
Paroaria coronata | red-crested cardinal
Regardless, their physical appearance is strikingly similar with their red head and crest while differing in their grey wings and white underbelly. This species is an introduced and well established resident in Hawaiʻi and has become a common sighting at mainly beach parks.
