Unmarshalling a arbitrary json list. There are several examples of nested list but not at root

unmarshal.go

// try here: https://play.golang.org/p/SChzGHXYgOU
package main

import (
	"encoding/json"
	"fmt"
)

func main() {
	birdJson := `{"birds":[{"pigeon":"likes to perch on rocks","eagle":"bird of prey"}]}`
	var result map[string]interface{}
	json.Unmarshal([]byte(birdJson), &result)

	birds := result["birds"].([]interface{})

	
	for _, key := range birds {
		t := key.(map[string]interface{})
		for k, v := range t {
			fmt.Println(k,v)
			//pigeon likes to perch on rocks
			//eagle bird of prey
		}
	}
