I'm wondering if some Great Blue Heron behavior I'm seeing lately is unusual or if others have seen it. A pair of GBH have built a nest in a tall pine tree behind my home and appear to be going through mating rituals. What's unusual to me is: the timing (they began in mid-May when most herons in south Texas were mating in March); the location (GBH typically nest in colonies or a rookery type setting, while this one is a lone nest); and the lack of consistent attention to the nest (it's vacant most days for a few hours in late morning to early afternoon). Here are a couple of example photos I've taken - can't get close or a look down perspective - nest is at top of a 75 foot pine tree about 250 feet from my deck, so I can only look up at it with a long lens. I have seen the pair mating recently. I'm asking this question because I've never seen a lone GBH nest like this before. I've always seen them in places that look like this: Taken late April at Bird Island, Lake Conroe, TX from a rocking pontoon boat (thank you active VR mode!) Anyone out there have any feedback?
