Answer: no, but I also found this.
Since a bird’s body temperature is much higher than that of humans—a golden crowned kinglet was once found to have a body temperature of 111 degrees Fahrenheit—it’s doubly important for them to cool off in a hurry. Proteins that shuttle vital information to a bird’s organs begin to break apart at temperatures that are only slightly higher.
Huh, so do all birds really have higher body temperatures than mammals?
Answer: yes. Between 1.87°C (3.66° F) higher at night to 2.43°C (4.374° F) during the day, on average.
Some other fun facts:
- The smaller the bird the higher its body temperature, generally. Flightless birds also typically have lower body temperatures.
- Many birds can enter torpor, in which their body temperatures fall to 18–20°C (64.4–68°F).
- Some birds estivate, which is like hibernation for warm temperatures. In estivation body temperatures can drop as low as 4.5–7°C (40.1–44.6°C), which suggests that in avian estivation outside temperatures don't need to be particularly warm.
