Intake Examination:
- Blood Draw — Collect blood to run a packed cell volume (PCV) and total protein (TP). If unable to obtain a blood sample, use treatment protocol 1 until you are able to obtain a sample.
- Temperature — Stop exam if below 38ºC (100ºF). Warm the bird before continuing.
Place seabirds in a room warmed to no less than 24-25ºC (75-77ºF). If the bird’s temperature does not rise to normal (39-41ºC or 102-106ºF) within approximately an hour or if the bird’s temperature is dangerously low, place a space heater in front of the crate, and possibly place a heating pad underneath the crate. Place a towel between the cage and the pad. Monitor the bird closely by visually watching the bird as well as taking its temperature often.
- Weight — See Table 1 below
Table 1. Normal body weight in seabirds *
Species, common name | Species, scientific name | Normal weight range (grams) |
Cormorant, Brandt’s | Phalacrocorax penicillatus | 2103 |
Cormorant, Double-crested | Phalacorax auritus | 1400-2000 |
Grebe, Clark’s | Aechmophorus clarkii | 800-900 |
Grebe, Eared | Podiceps nigricollis | 218-375 |
Grebe, Horned | Podiceps auritus | 327-528 |
Grebe, Pied-billed | Podilymbus podiceps | 343-551 |
Grebe, Western | Aechmophorus occidentalis | 795-900** |
Gull, Western | Larus occidentalis | 700-1000 |
Loon, Common | Gavia immer | 3800-4480 |
Loon, Pacific | Gavia pacifica | 1400-1700 |
Loon, Red-Throated | Gavia stellata | 1150-1980 |
Murre, Common | Uria aalge | 600-700 |
Pelican, Brown | Pelecanus occidentalis | 2500-3700 |
* Weights vary due to sex and season ** Body weight up to 1818 grams has been seen in Western grebes. |
Please note: When using one of the treatment protocols described below, EmerAid Carnivore can be substituted short-term for EmerAid Piscivore, the first semi-elemental diet designed for the critically ill fish-eater.
Treatment Protocol 1 — Starvation
(PCV < 30%, TP < 2 g/dL)*
Quantity per tube feeding – 7% of body weight (kg)
For instance a 1,000-gram bird could be gavaged up to 70 ml of fluid. Administer the fluid very slowly, and stop if fluid begins to well up in the back of the throat. If the bird is unable to hold 7%, then gradually work up to this volume.
Upon Intake: | Gavage or tube warm lactated Ringer’s solution (LRS) per os (PO) or subcutaneously (SC) |
1 hour later: | 25% dilution of EmerAid Piscivore |
2 hours later: | LRS (PO, SC) |
1 hour later: | 35% dilution EmerAid Piscivore |
2 hours later: | LRS |
1 hour later: | 45% dilution EmerAid Piscivore |
2nd Day* | LRS |
1 hour later: | 55% dilution EmerAid Piscivore |
2 hours later: | 65% dilution EmerAid Piscivore |
2 hours later: | 75% dilution EmerAid Piscivore |
2 hours later: | 85% dilution EmerAid Piscivore |
2 hours later: | 100% EmerAid Piscivore, made as directed per label instructions |
2 hours later: | LRS |
NOTE: If bird is still dehydrated, you may add another LRS mid-day replacing one EmerAid tube feeding.
Treatment Protocol 2 — Severe Starvation
(PCV < 20%, TP < 1 g/dL)*
Quantity per tube feeding – 7% of body weight (kg)
For instance a 1,000-gram bird could be gavaged up to 70 ml of fluid. Administer the fluid very slowly, and stop if fluid begins to well up in the back of the throat. If the bird is unable to hold 7%, then gradually work up to this volume.
Intake | Lactated Ringer's solution (LRS) (PO, SC) |
1 hour later: | 10% EmerAid Piscivore |
2 hours later: | LRS |
1 hour later: | 20% EmerAid Piscivore |
2 hours later: | LRS |
1 hour later: | 30% EmerAid Piscivore |
2 hours later: | LRS |
2nd Day* | LRS |
Same as Day 1 | Except give one LRS tubing first, and then give 40% EmerAid Piscivore feedings all day. |
3rd Day* | Recheck blood and assess bird’s overall condition |
Same as Day 2 | Except give one LRS tubing first, and then give 50% EmerAid Piscivore feedings all day. |
Continue until blood levels and bird’s energy can tolerate higher percentages. In rare cases, it may take up to 4-5 days for a severely emaciated bird to tolerate EmerAid as directed on the label, and possibly 5-6 days to eat solid food.
These protocols are not an exact science, but merely guidelines. Originally these protocols were used for starving and emaciated pelicans, but they are now used for all seabirds in similar states.
