That is very close. The calls from the birds near my house are even closer sounding to the "Creature from the Black Lagoon" chord. It might be due to my distance from them (they are 50-100 meters from me; I think that sound clip was recorded near to the bird) or perhaps regional differences in the species.
When the similarity hit me I actually stood up (I was weeding the garden); sort of an "Ah-ha!" moment.
