rostral issue on Brown Shrike? KL, Malaysia (1 Viewer)

Kuala Lumpur, Malaysia, couple days ago.

I've seen this individual around, and decided to attempt a substantial closeup to no avail (trying to take photos with a lousy d3400 sensor is like eating rice with chopsticks); however, I noticed the unusual overlapping tomia. Doesn't normal like it but I don't think I'm experienced enough to say anything... So what's this?

Hi, have you mirrored/inverted any of the 2 photos in the OP post? Or are they actually showing the left and right sides of the head respectively?

My question above comes from the fact the bill looks perfectly normal, no mandibles crossed whatsoever to my eyes (both sides in view). It looks to me like a thin bit of debris is stuck to the culmen in a funny way (perhaps dried meat from an earlier meal? or a bit of an insect gut? remember these birds are the butchers of the passerine world, so their bills do get messy). I really can't see this as the lower mandible piercing the upper, as there would be further evidences of such a traumatic event around the place the "thingy" is sticking out.

A common deformity across many species.

No. The mandibular rostrum is penetrating the maxillary rostrum.
